//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

 * This object provides a utility for producing rich Error messages within
 * Angular. It can be called as follows:
 *
 * var exampleMinErr = minErr('example');
 * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
 *
 * The above creates an instance of minErr in the example namespace. The
 * resulting error will have a namespaced error code of example.one.  The
 * resulting error will replace {0} with the value of foo, and {1} with the
 * value of bar. The object is not restricted in the number of arguments it can
 * take.
 *
 * If fewer arguments are specified than necessary for interpolation, the extra
 * interpolation markers will be preserved in the final string.
 *
 * Since data will be parsed statically during a build step, some restrictions
 * are applied with respect to how minErr instances are created and called.
 * Instances should have names of the form namespaceMinErr for a minErr created
 * using minErr('namespace') . Error codes, namespaces and template strings
 * should all be static strings, not variables or general expressions.
 *
 * @param {string} module The namespace to use for the new minErr instance.
 * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
 *   error from returned function, for cases when a particular type of error is useful.
 * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

/**
 * @ngdoc function
 * @name angular.copy
 * @module ng
 * @kind function
 *
 * @description
 * Creates a deep copy of `source`, which should be an object or an array.
 *
 * * If no destination is supplied, a copy of the object or array is created.
 * * If a destination is provided, all of its elements (for arrays) or properties (for objects)
 *   are deleted and then all elements/properties from the source are copied to it.
 * * If `source` is not an object or array (inc. `null` and `undefined`), `source` is returned.
 * * If `source` is identical to `destination` an exception will be thrown.
 *
 * <br />
 * <div class="alert alert-warning">
 *   Only enumerable properties are taken into account. Non-enumerable properties (both on `source`
 *   and on `destination`) will be ignored.
 * </div>
 *
 * @param {*} source The source that will be used to make a copy.
 *                   Can be any type, including primitives, `null`, and `undefined`.
 * @param {(Object|Array)=} destination Destination into which the source is copied. If
 *     provided, must be of the same type as `source`.
 * @returns {*} The copy or updated `destination`, if `destination` was specified.

 * @ngdoc directive

 *
 * @element ANY
 * @param {angular.Module} ngApp an optional application
 *   {@link angular.module module} name to load.
 * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
 *   created in "strict-di" mode. This means that the application will fail to invoke functions which

 *   tracking down the root of these bugs.
 *
 * @description
 *
 * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
 * designates the **root element** of the application and is typically placed near the root element
 * of the page - e.g. on the `<body>` or `<html>` tags.
 *
 * There are a few things to keep in mind when using `ngApp`:
 * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
 *   found in the document will be used to define the root element to auto-bootstrap as an
 *   application. To run multiple applications in an HTML document you must manually bootstrap them using
 *   {@link angular.bootstrap} instead.
 * - AngularJS applications cannot be nested within each other.
 * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
 *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
 *   {@link ngRoute.ngView `ngView`}.
 *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
 *   causing animations to stop working and making the injector inaccessible from outside the app.
 *
 * You can specify an **AngularJS module** to be used as the root module for the application.  This
 * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
 * should contain the application code needed or have dependencies on other modules that will
 * contain the code. See {@link angular.module} for more information.
 *
 * In the example below if the `ngApp` directive were not placed on the `html` element then the
 * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
 * would not be resolved to `3`.
 *
 * `ngApp` is the easiest, and most common way to bootstrap an application.
 *
 <example module="ngAppDemo">
   <file name="index.html">
   <div ng-controller="ngAppDemoController">
     I can add: {{a}} + {{b}} =  {{ a+b }}
   </div>
   </file>
   <file name="script.js">
   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
     $scope.a = 1;
     $scope.b = 2;
   });
   </file>
 </example>
 *
 * Using `ngStrictDi`, you would see something like this:
 *
 <example ng-app-included="true">
   <file name="index.html">
   <div ng-app="ngAppStrictDemo" ng-strict-di>
       <div ng-controller="GoodController1">
           I can add: {{a}} + {{b}} =  {{ a+b }}

           <p>This renders because the controller does not fail to
              instantiate, by using explicit annotation style (see
              script.js for details)
           </p>
       </div>

       <div ng-controller="GoodController2">
           Name: <input ng-model="name"><br />
           Hello, {{name}}!

           <p>This renders because the controller does not fail to

              (see script.js for details)

              strict mode). As such, the content of this section is not

     * The `angular.module` is a global place for creating, registering and retrieving Angular

     * # Module
     *
     * A module is a collection of services, directives, controllers, filters, and configuration information.
     * `angular.module` is used to configure the {@link auto.$injector $injector}.
     *
     * ```js
     * // Create a new module
     * var myModule = angular.module('myModule', []);
     *
     * // register a new service
     * myModule.value('appName', 'MyCoolApp');

     *   // Configure existing providers
     *   $locationProvider.hashPrefix('!');
     * }]);
     * ```
     *

     * ```
     *
     * However it's more likely that you'll just use

/**
 * @ngdoc function
 * @name angular.element
 * @module ng
 * @kind function
 *
 * @description
 * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
 *
 * If jQuery is available, `angular.element` is an alias for the
 * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
 * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
 *
 * jqLite is a tiny, API-compatible subset of jQuery that allows
 * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
 * commonly needed functionality with the goal of having a very small footprint.
 *
 * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
 * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
 * specific version of jQuery if multiple versions exist on the page.
 *
 * <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
 * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
 *
 * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
 * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
 * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
 *
 * ## Angular's jqLite
 * jqLite provides only the following jQuery methods:
 *
 * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
 * - [`after()`](http://api.jquery.com/after/)
 * - [`append()`](http://api.jquery.com/append/)
 * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
 * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
 * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
 * - [`clone()`](http://api.jquery.com/clone/)
 * - [`contents()`](http://api.jquery.com/contents/)
 * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
 *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
 * - [`data()`](http://api.jquery.com/data/)
 * - [`detach()`](http://api.jquery.com/detach/)
 * - [`empty()`](http://api.jquery.com/empty/)
 * - [`eq()`](http://api.jquery.com/eq/)
 * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
 * - [`hasClass()`](http://api.jquery.com/hasClass/)
 * - [`html()`](http://api.jquery.com/html/)
 * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
 * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
 * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
 * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
 * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
 * - [`prepend()`](http://api.jquery.com/prepend/)
 * - [`prop()`](http://api.jquery.com/prop/)
 * - [`ready()`](http://api.jquery.com/ready/)
 * - [`remove()`](http://api.jquery.com/remove/)
 * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
 * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
 * - [`removeData()`](http://api.jquery.com/removeData/)
 * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
 * - [`text()`](http://api.jquery.com/text/)
 * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
 * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
 * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter
 * - [`val()`](http://api.jquery.com/val/)
 * - [`wrap()`](http://api.jquery.com/wrap/)
 *
 * ## jQuery/jqLite Extras
 * Angular also provides the following additional methods and events to both jQuery and jqLite:
 *
 * ### Events
 * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
 *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
 *    element before it is removed.
 *
 * ### Methods
 * - `controller(name)` - retrieves the controller of the current element or its parent. By default
 *   retrieves controller associated with the `ngController` directive. If `name` is provided as
 *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
 *   `'ngModel'`).
 * - `injector()` - retrieves the injector of the current element or its parent.
 * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
 *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
 *   be enabled.
 * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
 *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
 *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
 *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
 * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
 *   parent element is reached.
 *
 * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
 * https://github.com/angular/angular.js/issues/14251 for more information.
 *
 * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
 * @returns {Object} jQuery object.

 *
 * @param {Array.<string|Function>} modules A list of module functions or their aliases. See

 * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which

 * @returns {injector} Injector object. See {@link auto.$injector $injector}.
 *
 * @example
 * Typical usage
 * ```js
 *   // create an injector
 *   var $injector = angular.injector(['ng']);
 *
 *   // use the injector to kick off your application
 *   // use the type inference to auto inject arguments, or use implicit injection
 *   $injector.invoke(function($rootScope, $compile, $document) {
 *     $compile($document)($rootScope);

 * ```
 *
 * Sometimes you want to get access to the injector of a currently running Angular app
 * from outside Angular. Perhaps, you want to inject and compile some markup after the
 * application has been bootstrapped. You can do this using the extra `injector()` added
 * to JQuery/jqLite elements. See {@link angular.element}.
 *
 * *This is fairly rare but could be the case if a third party library is injecting the
 * markup.*
 *
 * In the following example a new block of HTML containing a `ng-controller`
 * directive is added to the end of the document body by JQuery. We then compile and link
 * it into the current AngularJS scope.
 *
 * ```js
 * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
 * $(document.body).append($div);
 *
 * angular.element(document).injector().invoke(function($compile) {
 *   var scope = angular.element($div).scope();

 *
 * `$injector` is used to retrieve object instances as defined by

 * # Injection Function Annotation
 *
 * JavaScript does not have annotations, and annotations are needed for dependency injection. The
 * following are all valid ways of annotating function with injection arguments and are equivalent.
 *
 * ```js
 *   // inferred (only works if code not minified/obfuscated)
 *   $injector.invoke(function(serviceA){});
 *
 *   // annotated
 *   function explicit(serviceA) {};
 *   explicit.$inject = ['serviceA'];
 *   $injector.invoke(explicit);
 *
 *   // inline
 *   $injector.invoke(['serviceA', function(serviceA){}]);
 * ```
 *
 * ## Inference
 *
 * In JavaScript calling `toString()` on a function returns the function definition. The definition
 * can then be parsed and the function arguments can be extracted. This method of discovering
 * annotations is disallowed when the injector is in strict mode.
 * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
 * argument names.
 *
 * ## `$inject` Annotation
 * By adding an `$inject` property onto a function the injection parameters can be specified.
 *
 * ## Inline
 * As an array of injection names, where the last item in the array is the function to call.

 *
 * @description
 * Returns an array of service names which the function is requesting for injection. This API is
 * used by the injector to determine which services need to be injected into the function when the
 * function is invoked. There are three ways in which the function can be annotated with the needed
 * dependencies.
 *
 * # Argument names
 *
 * The simplest form is to extract the dependencies from the arguments of the function. This is done
 * by converting the function into a string using `toString()` method and extracting the argument
 * names.
 * ```js
 *   // Given
 *   function MyController($scope, $route) {
 *     // ...
 *   }
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * ```
 *
 * You can disallow this method by using strict injection mode.
 *
 * This method does not work with code minification / obfuscation. For this reason the following
 * annotation strategies are supported.
 *
 * # The `$inject` property
 *
 * If a function has an `$inject` property and its value is an array of strings, then the strings
 * represent names of services to be injected into the function.
 * ```js
 *   // Given
 *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
 *     // ...
 *   }
 *   // Define function dependencies

 *   });
 *

 *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
 *     // ...
 *   };
 *   tmpFn.$inject = ['$compile', '$rootScope'];
 *   injector.invoke(tmpFn);
 *
 *   // To better support inline function the inline annotation is supported
 *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
 *     // ...
 *   }]);
 *
 *   // Therefore
 *   expect(injector.annotate(
 *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
 *    ).toEqual(['$compile', '$rootScope']);
 * ```
 *

/**
 * @ngdoc service
 * @name $provide
 *
 * @description
 *
 * The {@link auto.$provide $provide} service has a number of methods for registering components
 * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
 * {@link angular.Module}.
 *
 * An Angular **service** is a singleton object created by a **service factory**.  These **service
 * factories** are functions which, in turn, are created by a **service provider**.
 * The **service providers** are constructor functions. When instantiated they must contain a
 * property called `$get`, which holds the **service factory** function.
 *
 * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
 * correct **service provider**, instantiating it and then calling its `$get` **service factory**
 * function to get the instance of the **service**.
 *
 * Often services have no configuration options and there is no need to add methods to the service
 * provider.  The provider will be no more than a constructor function with a `$get` property. For
 * these cases the {@link auto.$provide $provide} service has additional helper methods to register
 * services without specifying a provider.
 *
 * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
 *     {@link auto.$injector $injector}
 * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
 *     providers and services.
 * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
 *     services, not providers.
 * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
 *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
 *     given factory function.
 * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
 *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
 *      a new object using the given constructor function.
 * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
 *      will be able to modify or replace the implementation of another service.
 *
 * See the individual methods for more information and examples.

/**
 * @ngdoc method
 * @name $provide#provider
 * @description
 *
 * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
 * are constructor functions, whose instances are responsible for "providing" a factory for a
 * service.
 *
 * Service provider names start with the name of the service they provide followed by `Provider`.
 * For example, the {@link ng.$log $log} service has a provider called
 * {@link ng.$logProvider $logProvider}.
 *
 * Service provider objects can have additional methods which allow configuration of the provider
 * and its service. Importantly, you can configure what kind of service is created by the `$get`
 * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
 * method {@link ng.$logProvider#debugEnabled debugEnabled}
 * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
 * console or not.
 *
 * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
                        'Provider'` key.
 * @param {(Object|function())} provider If the provider is:
 *
 *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
 *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
 *   - `Constructor`: a new instance of the provider will be created using
 *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
 *
 * @returns {Object} registered provider instance

 * @example
 *
 * The following example shows how to create a simple event tracking service and register it using
 * {@link auto.$provide#provider $provide.provider()}.
 *
 * ```js
 *  // Define the eventTracker provider
 *  function EventTrackerProvider() {
 *    var trackingUrl = '/track';
 *
 *    // A provider method for configuring where the tracked events should been saved
 *    this.setTrackingUrl = function(url) {
 *      trackingUrl = url;
 *    };
 *
 *    // The service factory function
 *    this.$get = ['$http', function($http) {
 *      var trackedEvents = {};
 *      return {
 *        // Call this to track an event
 *        event: function(event) {
 *          var count = trackedEvents[event] || 0;
 *          count += 1;
 *          trackedEvents[event] = count;
 *          return count;
 *        },
 *        // Call this to save the tracked events to the trackingUrl
 *        save: function() {
 *          $http.post(trackingUrl, trackedEvents);
 *        }
 *      };
 *    }];
 *  }
 *
 *  describe('eventTracker', function() {
 *    var postSpy;
 *
 *    beforeEach(module(function($provide) {
 *      // Register the eventTracker provider
 *      $provide.provider('eventTracker', EventTrackerProvider);
 *    }));
 *
 *    beforeEach(module(function(eventTrackerProvider) {
 *      // Configure eventTracker provider
 *      eventTrackerProvider.setTrackingUrl('/custom-track');
 *    }));
 *
 *    it('tracks events', inject(function(eventTracker) {
 *      expect(eventTracker.event('login')).toEqual(1);
 *      expect(eventTracker.event('login')).toEqual(2);
 *    }));
 *
 *    it('saves to the tracking url', inject(function(eventTracker, $http) {
 *      postSpy = spyOn($http, 'post');
 *      eventTracker.event('login');
 *      eventTracker.save();
 *      expect(postSpy).toHaveBeenCalled();

/**

 * @description
 *
 * Register a **value service** with the {@link auto.$injector $injector}, such as a string, a
 * number, an array, an object or a function. This is short for registering a service where its
 * provider's `$get` property is a factory function that takes no arguments and returns the **value
 * service**. That also means it is not possible to inject other services into a value service.
 *
 * Value services are similar to constant services, except that they cannot be injected into a

 * an Angular {@link auto.$provide#decorator decorator}.
 *
 * @param {string} name The name of the instance.

/**
 * @ngdoc method
 * @name $provide#decorator
 * @description
 *
 * Register a **decorator function** with the {@link auto.$injector $injector}. A decorator function
 * intercepts the creation of a service, allowing it to override or modify the behavior of the
 * service. The return value of the decorator function may be the original service, or a new service
 * that replaces (or wraps and delegates to) the original service.
 *
 * You can find out more about using decorators in the {@link guide/decorators} guide.
 *
 * @param {string} name The name of the service to decorate.
 * @param {Function|Array.<string|Function>} decorator This function will be invoked when the service needs to be
 *    provided and should return the decorated service instance. The function is called using
 *    the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
 *    Local injection arguments:
 *
 *    * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,
 *      decorated or delegated to.
 *
 * @example
 * Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting
 * calls to {@link ng.$log#error $log.warn()}.
 * ```js
 *   $provide.decorator('$log', ['$delegate', function($delegate) {

 *     return $delegate;

   * @requires $location
   * @requires $rootScope
   *
   * @description
   * When called, it scrolls to the element related to the specified `hash` or (if omitted) to the
   * current value of {@link ng.$location#hash $location.hash()}, according to the rules specified
   * in the
   * [HTML5 spec](http://www.w3.org/html/wg/drafts/html/master/browsers.html#an-indicated-part-of-the-document).
   *
   * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
   * match any anchor whenever it changes. This can be disabled by calling
   * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
   *
   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
   * vertical scroll-offset (either fixed or dynamic).
   *
   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
   *                       {@link ng.$location#hash $location.hash()} will be used.
   *
   * @property {(number|function|jqLite)} yOffset
   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
   * positioned elements at the top of the page, such as navbars, headers etc.
   *
   * `yOffset` can be specified in various ways:
   * - **number**: A fixed number of pixels to be used as offset.<br /><br />
   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
   *   a number representing the offset (in pixels).<br /><br />
   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
   *   the top of the page to the element's bottom will be used as offset.<br />
   *   **Note**: The element will be taken into account only as long as its `position` is set to
   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
   *   their height and/or positioning according to the viewport's size.
   *
   * <br />
   * <div class="alert alert-warning">
   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
   * not some child element.

 *
 * The compilation is a process of walking the DOM tree and matching DOM elements to

 *
 * <div class="alert alert-warning">
 * **Note:** This document is an in-depth reference of all directive options.
 * For a gentle introduction to directives with examples of common use cases,
 * see the {@link guide/directive directive guide}.
 * </div>
 *
 * ## Comprehensive Directive API
 *
 * There are many different options for a directive.
 *
 * The difference resides in the return value of the factory function.
 * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
 * that defines the directive properties, or just the `postLink` function (all other properties will have
 * the default values).
 *
 * <div class="alert alert-success">
 * **Best Practice:** It's recommended to use the "directive definition object" form.
 * </div>
 *
 * Here's an example directive declared with a Directive Definition Object:
 *
 * ```js
 *   var myModule = angular.module(...);
 *
 *   myModule.directive('directiveName', function factory(injectables) {
 *     var directiveDefinitionObject = {
 *       priority: 0,
 *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
 *       // or
 *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
 *       transclude: false,
 *       restrict: 'A',
 *       templateNamespace: 'html',
 *       scope: false,
 *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
 *       controllerAs: 'stringIdentifier',
 *       bindToController: false,
 *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
 *       compile: function compile(tElement, tAttrs, transclude) {
 *         return {
 *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
 *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
 *         }
 *         // or
 *         // return function postLink( ... ) { ... }
 *       },
 *       // or
 *       // link: {
 *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
 *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
 *       // }
 *       // or
 *       // link: function postLink( ... ) { ... }
 *     };
 *     return directiveDefinitionObject;
 *   });
 * ```
 *
 * <div class="alert alert-warning">
 * **Note:** Any unspecified options will use the default value. You can see the default values below.
 * </div>
 *
 * Therefore the above can be simplified as:
 *
 * ```js
 *   var myModule = angular.module(...);
 *
 *   myModule.directive('directiveName', function factory(injectables) {
 *     var directiveDefinitionObject = {
 *       link: function postLink(scope, iElement, iAttrs) { ... }
 *     };
 *     return directiveDefinitionObject;
 *     // or
 *     // return function postLink(scope, iElement, iAttrs) { ... }
 *   });
 * ```
 *
 * ### Life-cycle hooks
 * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
 * directive:
 * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
 *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
 *   this element). This is a good place to put initialization code for your controller.
 * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
 *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
 *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
 *   component such as cloning the bound value to prevent accidental mutation of the outer value.
 * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
 *   changes. Any actions that you wish to take in response to the changes that you detect must be
 *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
 *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
 *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
 *   if detecting changes, you must store the previous value(s) for comparison to the current values.
 * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
 *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
 *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
 *   components will have their `$onDestroy()` hook called before child components.
 * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
 *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
 *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
 *   they are waiting for their template to load asynchronously and their own compilation and linking has been
 *   suspended until that occurs.
 *
 * #### Comparison with Angular 2 life-cycle hooks
 * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
 * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
 *
 * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
 * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
 *   In Angular 2 you can only define hooks on the prototype of the Component class.
 * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
 *   `ngDoCheck` in Angular 2
 * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
 *   propagated throughout the application.
 *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
 *   error or do nothing depending upon the state of `enableProdMode()`.
 *
 * #### Life-cycle hook examples
 *
 * This example shows how you can check for mutations to a Date object even though the identity of the object
 * has not changed.
 *
 * <example name="doCheckDateExample" module="do-check-module">
 *   <file name="app.js">
 *     angular.module('do-check-module', [])
 *       .component('app', {
 *         template:
 *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
 *           'Date: {{ $ctrl.date }}' +
 *           '<test date="$ctrl.date"></test>',
 *         controller: function() {
 *           this.date = new Date();
 *           this.month = this.date.getMonth();
 *           this.updateDate = function() {
 *             this.date.setMonth(this.month);
 *           };
 *         }
 *       })
 *       .component('test', {
 *         bindings: { date: '<' },
 *         template:
 *           '<pre>{{ $ctrl.log | json }}</pre>',
 *         controller: function() {
 *           var previousValue;
 *           this.log = [];
 *           this.$doCheck = function() {
 *             var currentValue = this.date && this.date.valueOf();
 *             if (previousValue !== currentValue) {
 *               this.log.push('doCheck: date mutated: ' + this.date);
 *               previousValue = currentValue;
 *             }
 *           };
 *         }
 *       });
 *   </file>
 *   <file name="index.html">
 *     <app></app>
 *   </file>
 * </example>
 *
 * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
 * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
 * arrays or objects can have a negative impact on your application performance)
 *
 * <example name="doCheckArrayExample" module="do-check-module">
 *   <file name="index.html">
 *     <div ng-init="items = []">
 *       <button ng-click="items.push(items.length)">Add Item</button>
 *       <button ng-click="items = []">Reset Items</button>
 *       <pre>{{ items }}</pre>
 *       <test items="items"></test>
 *     </div>
 *   </file>
 *   <file name="app.js">
 *      angular.module('do-check-module', [])
 *        .component('test', {
 *          bindings: { items: '<' },
 *          template:
 *            '<pre>{{ $ctrl.log | json }}</pre>',
 *          controller: function() {
 *            this.log = [];
 *
 *            this.$doCheck = function() {
 *              if (this.items_ref !== this.items) {
 *                this.log.push('doCheck: items changed');
 *                this.items_ref = this.items;
 *              }
 *              if (!angular.equals(this.items_clone, this.items)) {
 *                this.log.push('doCheck: items mutated');
 *                this.items_clone = angular.copy(this.items);
 *              }
 *            };
 *          }
 *        });
 *   </file>
 * </example>

 *
 * ### Directive Definition Object
 *
 * The directive definition object provides instructions to the {@link ng.$compile
 * compiler}. The attributes are:
 *
 * #### `multiElement`
 * When this property is set to true, the HTML compiler will collect DOM nodes between
 * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
 * together as the directive elements. It is recommended that this feature be used on directives
 * which are not strictly behavioral (such as {@link ngClick}), and which
 * do not manipulate or replace child nodes (such as {@link ngInclude}).
 *
 * #### `priority`
 * When there are multiple directives defined on a single DOM element, sometimes it
 * is necessary to specify the order in which the directives are applied. The `priority` is used
 * to sort the directives before their `compile` functions get called. Priority is defined as a
 * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
 * are also run in priority order, but post-link functions are run in reverse order. The order
 * of directives with the same priority is undefined. The default priority is `0`.
 *
 * #### `terminal`
 * If set to true then the current `priority` will be the last set of directives
 * which will execute (any directives at the current priority will still execute
 * as the order of execution on same `priority` is undefined). Note that expressions
 * and other directives used in the directive's template will also be excluded from execution.
 *
 * #### `scope`
 * The scope property can be `true`, an object or a falsy value:
 *
 * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
 *
 * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
 * the directive's element. If multiple directives on the same element request a new scope,
 * only one new scope is created. The new scope rule does not apply for the root of the template
 * since the root of the template always gets a new scope.
 *
 * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
 * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
 * scope. This is useful when creating reusable components, which should not accidentally read or modify
 * data in the parent scope.
 *
 * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
 * directive's element. These local properties are useful for aliasing values for templates. The keys in
 * the object hash map to the name of the property on the isolate scope; the values define how the property
 * is bound to the parent scope, via matching attributes on the directive's element:
 *
 * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
 *   always a string since DOM attributes are strings. If no `attr` name is specified then the
 *   attribute name is assumed to be the same as the local name. Given `<my-component
 *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
 *   the directive's scope property `localName` will reflect the interpolated value of `hello
 *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
 *   scope. The `name` is read from the parent scope (not the directive's scope).
 *
 * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
 *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
 *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
 *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
 *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
 *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
 *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
 *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
 *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
 *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
 *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
 *   method is used for tracking changes, and the equality check is based on object identity.
 *   However, if an object literal or an array literal is passed as the binding expression, the
 *   equality check is done by value (using the {@link angular.equals} function). It's also possible
 *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
 *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
 *
  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
 *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
 *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
 *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
 *
 *   For example, given `<my-component my-attr="parentModel">` and directive definition of
 *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
 *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
 *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
 *   two caveats:
 *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
 *     sets the same value. That means if your bound value is an object, changes to its properties
 *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
 *     2. one-way binding watches changes to the **identity** of the parent value. That means the
 *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
 *     to the value has changed. In most cases, this should not be of concern, but can be important
 *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
 *     If you now change a property of the object in your parent scope, the change will not be
 *     propagated to the isolated scope, because the identity of the object on the parent scope
 *     has not changed. Instead you must assign a new object.
 *
 *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
 *   back to the parent. However, it does not make this completely impossible.
 *
 * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
 *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
 *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
 *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
 *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
 *   via an expression to the parent scope. This can be done by passing a map of local variable names
 *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
 *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
 *
 * In general it's possible to apply more than one directive to one element, but there might be limitations
 * depending on the type of scope required by the directives. The following points will help explain these limitations.
 * For simplicity only two directives are taken into account, but it is also applicable for several directives:
 *
 * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
 * * **child scope** + **no scope** =>  Both directives will share one single child scope
 * * **child scope** + **child scope** =>  Both directives will share one single child scope
 * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
 * its parent's scope
 * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
 * be applied to the same element.
 * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
 * cannot be applied to the same element.
 *
 *
 * #### `bindToController`
 * This property is used to bind scope properties directly to the controller. It can be either
 * `true` or an object hash with the same format as the `scope` property. Additionally, a controller
 * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller
 * definition: `controller: 'myCtrl as myAlias'`.
 *
 * When an isolate scope is used for a directive (see above), `bindToController: true` will
 * allow a component to have its properties bound to the controller, rather than to scope.
 *
 * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
 * properties. You can access these bindings once they have been initialized by providing a controller method called
 * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
 * initialized.
 *
 * <div class="alert alert-warning">
 * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
 * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
 * code that relies upon bindings inside a `$onInit` method on the controller, instead.
 * </div>
 *
 * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
 * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
 * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
 * scope (useful for component directives).
 *
 * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
 *
 *
 * #### `controller`
 * Controller constructor function. The controller is instantiated before the
 * pre-linking phase and can be accessed by other directives (see
 * `require` attribute). This allows the directives to communicate with each other and augment
 * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
 *
 * * `$scope` - Current scope associated with the element
 * * `$element` - Current element
 * * `$attrs` - Current attributes object for the element
 * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
 *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
 *    * `scope`: (optional) override the scope.
 *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
 *    * `futureParentElement` (optional):
 *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
 *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
 *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
 *          and when the `cloneLinkinFn` is passed,
 *          as those elements need to created and cloned in a special way when they are defined outside their
 *          usual containers (e.g. like `<svg>`).
 *        * See also the `directive.templateNamespace` property.
 *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
 *      then the default translusion is provided.
 *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
 *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
 *
 * #### `require`
 * Require another directive and inject its controller as the fourth argument to the linking function. The
 * `require` property can be a string, an array or an object:
 * * a **string** containing the name of the directive to pass to the linking function
 * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
 * linking function will be an array of controllers in the same order as the names in the `require` property
 * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
 * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
 * controllers.
 *
 * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
 * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
 * have been constructed but before `$onInit` is called.
 * If the name of the required controller is the same as the local name (the key), the name can be
 * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
 * See the {@link $compileProvider#component} helper for an example of how this can be used.
 * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
 * raised (unless no link function is specified and the required controllers are not being bound to the directive
 * controller, in which case error checking is skipped). The name can be prefixed with:
 *
 * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
 * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
 * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
 * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
 * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
 *   `null` to the `link` fn if not found.
 * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
 *   `null` to the `link` fn if not found.
 *
 *
 * #### `controllerAs`
 * Identifier name for a reference to the controller in the directive's scope.
 * This allows the controller to be referenced from the directive template. This is especially
 * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
 * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
 * `controllerAs` reference might overwrite a property that already exists on the parent scope.
 *
 *
 * #### `restrict`
 * String of subset of `EACM` which restricts the directive to a specific directive
 * declaration style. If omitted, the defaults (elements and attributes) are used.
 *
 * * `E` - Element name (default): `<my-directive></my-directive>`
 * * `A` - Attribute (default): `<div my-directive="exp"></div>`
 * * `C` - Class: `<div class="my-directive: exp;"></div>`
 * * `M` - Comment: `<!-- directive: my-directive exp -->`
 *
 *
 * #### `templateNamespace`
 * String representing the document type used by the markup in the template.
 * AngularJS needs this information as those elements need to be created and cloned
 * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
 *
 * * `html` - All root nodes in the template are HTML. Root nodes may also be
 *   top-level elements such as `<svg>` or `<math>`.
 * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
 * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
 *
 * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
 *
 * #### `template`
 * HTML markup that may:
 * * Replace the contents of the directive's element (default).
 * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
 * * Wrap the contents of the directive's element (if `transclude` is true).
 *
 * Value may be:
 *
 * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
 * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
 *   function api below) and returns a string value.
 *
 *
 * #### `templateUrl`
 * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
 *
 * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
 * for later when the template has been resolved.  In the meantime it will continue to compile and link
 * sibling and parent elements as though this element had not contained any directives.
 *
 * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
 * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
 * case when only one deeply nested directive has `templateUrl`.
 *
 * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
 *
 * You can specify `templateUrl` as a string representing the URL or as a function which takes two
 * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
 * a string value representing the url.  In either case, the template URL is passed through {@link
 * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
 *
 *
 * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
 * specify what the template should replace. Defaults to `false`.
 *
 * * `true` - the template will replace the directive's element.
 * * `false` - the template will replace the contents of the directive's element.
 *
 * The replacement process migrates all of the attributes / classes from the old element to the new
 * one. See the {@link guide/directive#template-expanding-directive
 * Directives Guide} for an example.
 *
 * There are very few scenarios where element replacement is required for the application function,
 * the main one being reusable custom components that are used within SVG contexts
 * (because SVG doesn't work with custom elements in the DOM tree).
 *
 * #### `transclude`
 * Extract the contents of the element where the directive appears and make it available to the directive.
 * The contents are compiled and provided to the directive as a **transclusion function**. See the
 * {@link $compile#transclusion Transclusion} section below.
 *
 *
 * #### `compile`
 *
 * ```js
 *   function compile(tElement, tAttrs, transclude) { ... }
 * ```
 *
 * The compile function deals with transforming the template DOM. Since most directives do not do
 * template transformation, it is not used often. The compile function takes the following arguments:
 *
 *   * `tElement` - template element - The element where the directive has been declared. It is
 *     safe to do template transformation on the element and child elements only.
 *
 *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
 *     between all directive compile functions.
 *
 *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
 *
 * <div class="alert alert-warning">
 * **Note:** The template instance and the link instance may be different objects if the template has
 * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
 * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
 * should be done in a linking function rather than in a compile function.
 * </div>

 * <div class="alert alert-warning">
 * **Note:** The compile function cannot handle directives that recursively use themselves in their
 * own templates or compile functions. Compiling these directives results in an infinite loop and
 * stack overflow errors.
 *
 * This can be avoided by manually using $compile in the postLink function to imperatively compile
 * a directive's template instead of relying on automatic template compilation via `template` or
 * `templateUrl` declaration or manual compilation inside the compile function.
 * </div>
 *
 * <div class="alert alert-danger">
 * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
 *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
 *   to the link function instead.
 * </div>

 * A compile function can have a return value which can be either a function or an object.
 *
 * * returning a (post-link) function - is equivalent to registering the linking function via the
 *   `link` property of the config object when the compile function is empty.
 *
 * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
 *   control when a linking function should be called during the linking phase. See info about
 *   pre-linking and post-linking functions below.
 *
 *
 * #### `link`
 * This property is used only if the `compile` property is not defined.
 *
 * ```js
 *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
 * ```
 *
 * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
 * executed after the template has been cloned. This is where most of the directive logic will be
 * put.
 *
 *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
 *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
 *
 *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
 *     manipulate the children of the element only in `postLink` function since the children have
 *     already been linked.
 *
 *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
 *     between all directive linking functions.
 *
 *   * `controller` - the directive's required controller instance(s) - Instances are shared
 *     among all directives, which allows the directives to use the controllers as a communication
 *     channel. The exact value depends on the directive's `require` property:
 *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
 *       * `string`: the controller instance
 *       * `array`: array of controller instances
 *
 *     If a required controller cannot be found, and it is optional, the instance is `null`,
 *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
 *
 *     Note that you can also require the directive's own controller - it will be made available like
 *     any other controller.
 *
 *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
 *     This is the same as the `$transclude` parameter of directive controllers,
 *     see {@link ng.$compile#-controller- the controller section for details}.
 *     `function([scope], cloneLinkingFn, futureParentElement)`.
 *
 * #### Pre-linking function
 *
 * Executed before the child elements are linked. Not safe to do DOM transformation since the
 * compiler linking function will fail to locate the correct elements for linking.
 *
 * #### Post-linking function
 *
 * Executed after the child elements are linked.
 *
 * Note that child elements that contain `templateUrl` directives will not have been compiled
 * and linked since they are waiting for their template to load asynchronously and their own
 * compilation and linking has been suspended until that occurs.
 *
 * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
 * for their async templates to be resolved.
 *
 *
 * ### Transclusion
 *
 * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
 * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
 * scope from where they were taken.
 *
 * Transclusion is used (often with {@link ngTransclude}) to insert the
 * original contents of a directive's element into a specified place in the template of the directive.
 * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
 * content has access to the properties on the scope from which it was taken, even if the directive
 * has isolated scope.
 * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
 *
 * This makes it possible for the widget to have private state for its template, while the transcluded
 * content has access to its originating scope.
 *
 * <div class="alert alert-warning">
 * **Note:** When testing an element transclude directive you must not place the directive at the root of the
 * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
 * Testing Transclusion Directives}.
 * </div>
 *
 * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
 * directive's element, the entire element or multiple parts of the element contents:
 *
 * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
 * * `'element'` - transclude the whole of the directive's element including any directives on this
 *   element that defined at a lower priority than this directive. When used, the `template`
 *   property is ignored.
 * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
 *
 * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
 *
 * This object is a map where the keys are the name of the slot to fill and the value is an element selector
 * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
 * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
 *
 * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
 *
 * If the element selector is prefixed with a `?` then that slot is optional.
 *
 * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
 * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
 *
 * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
 * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
 * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
 * injectable into the directive's controller.
 *
 *
 * #### Transclusion Functions
 *
 * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
 * function** to the directive's `link` function and `controller`. This transclusion function is a special
 * **linking function** that will return the compiled contents linked to a new transclusion scope.
 *
 * <div class="alert alert-info">
 * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
 * ngTransclude will deal with it for us.
 * </div>
 *
 * If you want to manually control the insertion and removal of the transcluded content in your directive
 * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
 * object that contains the compiled DOM, which is linked to the correct transclusion scope.
 *
 * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
 * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
 * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
 *
 * <div class="alert alert-info">
 * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
 * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
 * </div>
 *
 * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
 * attach function**:
 *
 * ```js
 * var transcludedContent, transclusionScope;
 *
 * $transclude(function(clone, scope) {
 *   element.append(clone);
 *   transcludedContent = clone;
 *   transclusionScope = scope;
 * });
 * ```
 *
 * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
 * associated transclusion scope:
 *
 * ```js
 * transcludedContent.remove();
 * transclusionScope.$destroy();
 * ```
 *
 * <div class="alert alert-info">
 * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
 * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
 * then you are also responsible for calling `$destroy` on the transclusion scope.
 * </div>
 *
 * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
 * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
 * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
 *
 *
 * #### Transclusion Scopes
 *
 * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
 * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
 * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
 * was taken.
 *
 * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
 * like this:
 *
 * ```html
 * <div ng-app>
 *   <div isolate>
 *     <div transclusion>
 *     </div>
 *   </div>
 * </div>
 * ```
 *
 * The `$parent` scope hierarchy will look like this:
 *
   ```
   - $rootScope
     - isolate
       - transclusion
   ```
 *
 * but the scopes will inherit prototypically from different scopes to their `$parent`.
 *
   ```
   - $rootScope
     - transclusion
   - isolate
   ```
 *
 *
 * ### Attributes
 *
 * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
 * `link()` or `compile()` functions. It has a variety of uses.
 *
 * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
 *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
 *   to the attributes.
 *
 * * *Directive inter-communication:* All directives share the same instance of the attributes
 *   object which allows the directives to use the attributes object as inter directive
 *   communication.
 *
 * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
 *   allowing other directives to read the interpolated value.
 *
 * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
 *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
 *   the only way to easily get the actual value because during the linking phase the interpolation
 *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
 *
 * ```js
 * function linkingFn(scope, elm, attrs, ctrl) {
 *   // get the attribute value
 *   console.log(attrs.ngModel);
 *
 *   // change the attribute
 *   attrs.$set('ngModel', 'new value');
 *
 *   // observe changes to interpolated attribute
 *   attrs.$observe('ngModel', function(value) {
 *     console.log('ngModel has changed value to ' + value);
 *   });
 * }
 * ```
 *
 * ## Example
 *
 * <div class="alert alert-warning">
 * **Note**: Typically directives are registered with `module.directive`. The example below is
 * to illustrate how `$compile` works.

 *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
 *      * `scope` - is the current scope with which the linking function is working with.
 *
 *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
 *  keys may be used to control linking behavior:
 *
 *      * `parentBoundTranscludeFn` - the transclude function made available to
 *        directives; if given, it will be passed through to the link functions of
 *        directives found in `element` during compilation.
 *      * `transcludeControllers` - an object hash with keys that map controller names
 *        to a hash with the key `instance`, which maps to the controller instance;
 *        if given, it will make the controllers available to directives on the compileNode:
 *        ```
 *        {
 *          parent: {
 *            instance: parentControllerInstance
 *          }
 *        }
 *        ```
 *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
 *        the cloned elements; only needed for transcludes that are allowed to contain non html
 *        elements (e.g. SVG elements). See also the directive.controller property.
 *
 * Calling the linking function returns the element of the template. It is either the original
 * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
 *
 * After linking the view is not updated until after a call to $digest which typically is done by
 * Angular automatically.
 *
 * If you need access to the bound view, there are two ways to do it:
 *
 * - If you are not asking the linking function to clone the template, create the DOM element(s)
 *   before you send them to the compiler and keep this reference around.
 *   ```js
 *     var element = $compile('<p>{{total}}</p>')(scope);
 *   ```
 *
 * - if on the other hand, you need the element to be cloned, the view reference from the original
 *   example would not point to the clone, but rather to the original template that was cloned. In
 *   this case, you can access the clone via the cloneAttachFn:
 *   ```js
 *     var templateElement = angular.element('<p>{{total}}</p>'),
 *         scope = ....;
 *
 *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
 *       //attach the clone to DOM document at the right place
 *     });
 *
 *     //now we have reference to the cloned DOM via `clonedElement`
 *   ```
 *
 *
 * For information on how the compiler works, see the
 * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

   * @description
   * Register a **component definition** with the compiler. This is a shorthand for registering a special
   * type of directive, which represents a self-contained UI component in your application. Such components
   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
   *
   * Component definitions are very simple and do not require as much configuration as defining general
   * directives. Component definitions usually consist only of a template and a controller backing it.
   *
   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
   * `bindToController`. They always have **isolate scope** and are restricted to elements.
   *
   * Here are a few examples of how you would usually define components:
   *
   * ```js
   *   var myMod = angular.module(...);
   *   myMod.component('myComp', {
   *     template: '<div>My name is {{$ctrl.name}}</div>',
   *     controller: function() {
   *       this.name = 'shahar';
   *     }
   *   });
   *
   *   myMod.component('myComp', {
   *     template: '<div>My name is {{$ctrl.name}}</div>',
   *     bindings: {name: '@'}
   *   });
   *
   *   myMod.component('myComp', {
   *     templateUrl: 'views/my-comp.html',
   *     controller: 'MyCtrl',
   *     controllerAs: 'ctrl',
   *     bindings: {name: '@'}
   *   });
   *
   * ```
   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.

 * @ngdoc service
 * @name $exceptionHandler

 *
 * @description
 * Any uncaught exception in angular expressions is delegated to this service.
 * The default implementation simply delegates to `$log.error` which logs it into
 * the browser console.
 *
 * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
 * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
 *
 * ## Example:
 *
 * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
 * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
 * of `$log.error()`.
 *
 * ```js
 *   angular.
 *     module('exceptionOverwrite', []).
 *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
 *       return function myExceptionHandler(exception, cause) {
 *         logErrorsToBackend(exception, cause);
 *         $log.warn(exception, cause);
 *       };
 *     }]);
 * ```
 *
 * <hr />
 * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
 * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
 * (unless executed during a digest).
 *
 * If you wish, you can manually delegate exceptions, e.g.
 * `try { ... } catch(e) { $exceptionHandler(e); }`
 *
 * @param {Error} exception Exception associated with the error.
 * @param {string=} cause Optional information about the context in which

     * @description
     * The `$http` service is a core Angular service that facilitates communication with the remote
     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
     *
     * For unit testing applications that use `$http` service, see
     * {@link ngMock.$httpBackend $httpBackend mock}.
     *
     * For a higher level of abstraction, please check out the {@link ngResource.$resource
     * $resource} service.
     *
     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
     * it is important to familiarize yourself with these APIs and the guarantees they provide.
     *
     *
     * ## General usage
     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
     *
     * ```js
     *   // Simple GET request example:
     *   $http({
     *     method: 'GET',
     *     url: '/someUrl'
     *   }).then(function successCallback(response) {
     *       // this callback will be called asynchronously
     *       // when the response is available
     *     }, function errorCallback(response) {
     *       // called asynchronously if an error occurs
     *       // or server returns response with an error status.
     *     });
     * ```
     *
     * The response object has these properties:
     *
     *   - **data** – `{string|Object}` – The response body transformed with the transform
     *     functions.
     *   - **status** – `{number}` – HTTP status code of the response.
     *   - **headers** – `{function([headerName])}` – Header getter function.
     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
     *   - **statusText** – `{string}` – HTTP status text of the response.
     *
     * A response status code between 200 and 299 is considered a success status and will result in
     * the success callback being called. Any response status code outside of that range is
     * considered an error status and will result in the error callback being called.
     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
     * aborted, e.g. using a `config.timeout`.
     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
     * that the outcome (success or error) will be determined by the final response status code.
     *
     *
     * ## Shortcut methods
     *
     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
     * last argument.
     *
     * ```js
     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
     * ```
     *
     * Complete list of shortcut methods:
     *
     * - {@link ng.$http#get $http.get}
     * - {@link ng.$http#head $http.head}
     * - {@link ng.$http#post $http.post}
     * - {@link ng.$http#put $http.put}
     * - {@link ng.$http#delete $http.delete}
     * - {@link ng.$http#jsonp $http.jsonp}
     * - {@link ng.$http#patch $http.patch}
     *
     *
     * ## Writing Unit Tests that use $http
     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
     * request using trained responses.
     *
     * ```
     * $httpBackend.expectGET(...);
     * $http.get(...);
     * $httpBackend.flush();
     * ```
     *
     * ## Deprecation Notice
     * <div class="alert alert-danger">
     *   The `$http` legacy promise methods `success` and `error` have been deprecated.
     *   Use the standard `then` method instead.
     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
     * </div>
     *
     * ## Setting HTTP Headers
     *
     * The $http service will automatically add certain HTTP headers to all requests. These defaults
     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
     * object, which currently contains this default configuration:
     *
     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
     *   - `Accept: application/json, text/plain, * / *`
     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
     *   - `Content-Type: application/json`
     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
     *   - `Content-Type: application/json`
     *
     * To add or overwrite these defaults, simply add or remove a property from these configuration
     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
     * with the lowercased HTTP method name as the key, e.g.
     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
     *
     * The defaults can also be set at runtime via the `$http.defaults` object in the same
     * fashion. For example:
     *
     * ```
     * module.run(function($http) {
     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
     * });
     * ```
     *
     * In addition, you can supply a `headers` property in the config object passed when
     * calling `$http(config)`, which overrides the defaults without changing them globally.
     *
     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
     * Use the `headers` property, setting the desired header to `undefined`. For example:
     *
     * ```js
     * var req = {
     *  method: 'POST',
     *  url: 'http://example.com',
     *  headers: {
     *    'Content-Type': undefined
     *  },
     *  data: { test: 'test' }
     * }
     *
     * $http(req).then(function(){...}, function(){...});
     * ```
     *
     * ## Transforming Requests and Responses
     *
     * Both requests and responses can be transformed using transformation functions: `transformRequest`
     * and `transformResponse`. These properties can be a single function that returns
     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
     *
     * <div class="alert alert-warning">
     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
     * function will be reflected on the scope and in any templates where the object is data-bound.
     * To prevent this, transform functions should have no side-effects.
     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
     * </div>
     *
     * ### Default Transformations
     *
     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
     * `defaults.transformResponse` properties. If a request does not provide its own transformations
     * then these will be applied.
     *
     * You can augment or replace the default transformations by modifying these properties by adding to or
     * replacing the array.
     *
     * Angular provides the following default transformations:
     *
     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
     *
     * - If the `data` property of the request configuration object contains an object, serialize it
     *   into JSON format.
     *
     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
     *
     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
     *  - If JSON response is detected, deserialize it using a JSON parser.
     *
     *
     * ### Overriding the Default Transformations Per Request
     *
     * If you wish to override the request/response transformations only for a single request then provide
     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
     * into `$http`.
     *
     * Note that if you provide these properties on the config object the default transformations will be
     * overwritten. If you wish to augment the default transformations then you must include them in your
     * local transformation array.
     *
     * The following code demonstrates adding a new response transformation to be run after the default response
     * transformations have been run.
     *
     * ```js
     * function appendTransform(defaults, transform) {
     *
     *   // We can't guarantee that the default transformation is an array
     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
     *
     *   // Append the new transformation to the defaults
     *   return defaults.concat(transform);
     * }
     *
     * $http({
     *   url: '...',
     *   method: 'GET',
     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
     *     return doTransform(value);
     *   })
     * });
     * ```
     *
     *
     * ## Caching
     *
     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
     * set the config.cache value or the default cache value to TRUE or to a cache object (created
     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
     * precedence over the default cache value.
     *
     * In order to:
     *   * cache all responses - set the default cache value to TRUE or to a cache object
     *   * cache a specific response - set config.cache value to TRUE or to a cache object
     *
     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
     * then the default `$cacheFactory("$http")` object is used.
     *
     * The default cache value can be set by updating the
     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
     *
     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
     * the relevant cache object. The next time the same request is made, the response is returned
     * from the cache without sending a request to the server.
     *
     * Take note that:
     *
     *   * Only GET and JSONP requests are cached.
     *   * The cache key is the request URL including search parameters; headers are not considered.
     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
     *   * If multiple identical requests are made using the same cache, which is not yet populated,
     *     one request will be made to the server and remaining requests will return the same response.
     *   * A cache-control header on the response does not affect if or how responses are cached.
     *
     *
     * ## Interceptors
     *
     * Before you start creating interceptors, be sure to understand the
     * {@link ng.$q $q and deferred/promise APIs}.
     *
     * For purposes of global error handling, authentication, or any kind of synchronous or
     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
     * able to intercept requests before they are handed to the server and
     * responses before they are handed over to the application code that
     * initiated these requests. The interceptors leverage the {@link ng.$q
     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
     *
     * The interceptors are service factories that are registered with the `$httpProvider` by
     * adding them to the `$httpProvider.interceptors` array. The factory is called and
     * injected with dependencies (if specified) and returns the interceptor.
     *
     * There are two kinds of interceptors (and two kinds of rejection interceptors):
     *
     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
     *     modify the `config` object or create a new one. The function needs to return the `config`
     *     object directly, or a promise containing the `config` or a new `config` object.
     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
     *     resolved with a rejection.
     *   * `response`: interceptors get called with http `response` object. The function is free to
     *     modify the `response` object or create a new one. The function needs to return the `response`
     *     object directly, or as a promise containing the `response` or a new `response` object.
     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
     *     resolved with a rejection.
     *
     *
     * ```js
     *   // register the interceptor as a service
     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
     *     return {
     *       // optional method
     *       'request': function(config) {
     *         // do something on success
     *         return config;
     *       },
     *
     *       // optional method
     *      'requestError': function(rejection) {
     *         // do something on error
     *         if (canRecover(rejection)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(rejection);
     *       },
     *
     *
     *
     *       // optional method
     *       'response': function(response) {
     *         // do something on success
     *         return response;
     *       },
     *
     *       // optional method
     *      'responseError': function(rejection) {
     *         // do something on error
     *         if (canRecover(rejection)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(rejection);
     *       }
     *     };
     *   });
     *
     *   $httpProvider.interceptors.push('myHttpInterceptor');
     *
     *
     *   // alternatively, register the interceptor via an anonymous factory
     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
     *     return {
     *      'request': function(config) {
     *          // same as above
     *       },
     *
     *       'response': function(response) {
     *          // same as above
     *       }
     *     };
     *   });
     * ```
     *
     * ## Security Considerations
     *
     * When designing web applications, consider security threats from:
     *
     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
     *
     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
     * pre-configured with strategies that address these issues, but for this to work backend server
     * cooperation is required.
     *
     * ### JSON Vulnerability Protection
     *
     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
     * allows third party website to turn your JSON resource URL into
     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
     * Angular will automatically strip the prefix before processing it as JSON.
     *
     * For example if your server needs to return:
     * ```js
     * ['one','two']
     * ```
     *
     * which is vulnerable to attack, your server can return:
     * ```js
     * )]}',
     * ['one','two']
     * ```
     *
     * Angular will strip the prefix, before processing the JSON.
     *
     *
     * ### Cross Site Request Forgery (XSRF) Protection
     *
     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
     * which the attacker can trick an authenticated user into unknowingly executing actions on your
     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
     * The header will not be set for cross-domain requests.
     *
     * To take advantage of this, your server needs to set a token in a JavaScript readable session
     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
     * that only JavaScript running on your domain could have sent the request. The token must be
     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
     * making up its own tokens). We recommend that the token is a digest of your site's
     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
     * for added security.
     *
     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
     * or the per-request config object.
     *
     * In order to prevent collisions in environments where multiple Angular apps share the
     * same domain or subdomain, we recommend that each application uses unique cookie name.
     *
     * @param {object} config Object describing the request to be made and how it should be
     *    processed. The object has following properties:
     *
     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
     *      with the `paramSerializer` and appended as GET parameters.
     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
     *      HTTP headers to send to the server. If the return value of a function is null, the
     *      header will not be sent. Functions accept a config object as an argument.
     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
     *      The handler will be called in the context of a `$apply` block.
     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
     *      The handler will be called in the context of a `$apply` block.
     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
     *    - **transformRequest** –
     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      request body and headers and returns its transformed (typically serialized) version.
     *      See {@link ng.$http#overriding-the-default-transformations-per-request
     *      Overriding the Default Transformations}
     *    - **transformResponse** –
     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      response body, headers and status and returns its transformed (typically deserialized) version.
     *      See {@link ng.$http#overriding-the-default-transformations-per-request
     *      Overriding the Default Transformations}
     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
     *      prepare the string representation of request parameters (specified as an object).
     *      If specified as string, it is interpreted as function registered with the
     *      {@link $injector $injector}, which means you can create your own serializer
     *      by registering it as a {@link auto.$provide#service service}.
     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
     *      See {@link $http#caching $http Caching} for more information.
     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
     *      that should abort the request when resolved.
     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
     *      for more information.
     *    - **responseType** - `{string}` - see
     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
     *
     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
     *                        when the request succeeds or fails.
     *
     *
     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
     *   requests. This is primarily meant to be used for debugging purposes.
     *

     *
     * @description
     *
     * Compiles a string with markup into an interpolation function. This service is used by the
     * HTML {@link ng.$compile $compile} service for data binding. See
     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
     * interpolation markup.
     *
     *
     * ```js
     *   var $interpolate = ...; // injected
     *   var exp = $interpolate('Hello {{name | uppercase}}!');
     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
     * ```
     *
     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
     * `true`, the interpolation function will return `undefined` unless all embedded expressions
     * evaluate to a value other than `undefined`.
     *
     * ```js
     *   var $interpolate = ...; // injected
     *   var context = {greeting: 'Hello', name: undefined };
     *
     *   // default "forgiving" mode

     *   context.name = 'Angular';
     *   expect(exp(context)).toEqual('Hello Angular!');
     * ```
     *
     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
     *
     * #### Escaped Interpolation
     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
     * or binding.
     *
     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
     * degree, while also enabling code examples to work without relying on the
     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
     *
     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
     * interpolation start/end markers with their escaped counterparts.**
     *
     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
     * output when the $interpolate service processes the text. So, for HTML elements interpolated
     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
     * this is typically useful only when user-data is used in rendering a template from the server, or
     * when otherwise untrusted data is used by a directive.
     *
     * <example>
     *  <file name="index.html">
     *    <div ng-init="username='A user'">
     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
     *        </p>

     * @knownIssue
     * It is currently not possible for an interpolated expression to contain the interpolation end
     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
     *
     * @knownIssue
     * All directives and components must use the standard `{{` `}}` interpolation symbols
     * in their templates. If you change the application interpolation symbols the {@link $compile}
     * service will attempt to denormalize the standard symbols to the custom symbols.
     * The denormalization process is not clever enough to know not to replace instances of the standard
     * symbols where they would not normally be treated as interpolation symbols. For example in the following
     * code snippet the closing braces of the literal object will get incorrectly denormalized:
     *
     * ```
     * <div data-context='{"context":{"id":3,"type":"page"}}">
     * ```
     *
     * The workaround is to ensure that such instances are separated by whitespace:
     * ```
     * <div data-context='{"context":{"id":3,"type":"page"} }">
     * ```
     *

      * @description
      * Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
      * milliseconds.
      *
      * The return value of registering an interval function is a promise. This promise will be
      * notified upon each tick of the interval, and will be resolved after `count` iterations, or
      * run indefinitely if `count` is not defined. The value of the notification will be the
      * number of iterations that have run.
      * To cancel an interval, call `$interval.cancel(promise)`.
      *
      * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
      * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
      * time.
      *
      * <div class="alert alert-warning">
      * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
      * with them.  In particular they are not automatically destroyed when a controller's scope or a
      * directive's element are destroyed.
      * You should take this into consideration and make sure to always cancel the interval at the
      * appropriate moment.  See the example below for more details on how and when to do this.
      * </div>
      *
      * @param {function()} fn A function that should be called repeatedly.
      * @param {number} delay Number of milliseconds between each function call.
      * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
      *   indefinitely.
      * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
      *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
      * @param {...*=} Pass additional parameters to the executed function.

// Sandboxing Angular Expressions
// ------------------------------
// Angular expressions are generally considered safe because these expressions only have direct
// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
// obtaining a reference to native JS functions such as the Function constructor.
//
// As an example, consider the following Angular expression:
//
//   {}.toString.constructor('alert("evil JS code")')
//
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
// against the expression language, but not to prevent exploits that were enabled by exposing
// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
// practice and therefore we are not even trying to protect against interaction with an object
// explicitly exposed in this way.
//
// In general, it is not possible to access a Window object from an angular expression unless a
// window or some DOM object that has a reference to window is published onto a Scope.
// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
// native objects.

 *      * `literal` – `{boolean}` – whether the expression's top-level node is a JavaScript
 *        literal.
 *      * `constant` – `{boolean}` – whether the expression is made entirely of JavaScript

 *      * `assign` – `{?function(context, value)}` – if the expression is assignable, this will be
 *        set to a function to change its value on the given context.

/**
 * @ngdoc service
 * @name $q
 * @requires $rootScope
 *
 * @description
 * A service that helps you run functions asynchronously, and use their return values (or exceptions)
 * when they are done processing.
 *
 * This is an implementation of promises/deferred objects inspired by
 * [Kris Kowal's Q](https://github.com/kriskowal/q).
 *
 * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
 * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
 *
 * # $q constructor
 *
 * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
 * function as the first argument. This is similar to the native Promise implementation from ES6,
 * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
 *
 * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
 * available yet.
 *
 * It can be used like so:
 *
 * ```js
 *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
 *   // are available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
 *     return $q(function(resolve, reject) {
 *       setTimeout(function() {
 *         if (okToGreet(name)) {
 *           resolve('Hello, ' + name + '!');
 *         } else {
 *           reject('Greeting ' + name + ' is not allowed.');
 *         }
 *       }, 1000);
 *     });
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   });
 * ```
 *
 * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
 *
 * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
 *
 * However, the more traditional CommonJS-style usage is still available, and documented below.
 *
 * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
 * interface for interacting with an object that represents the result of an action that is
 * performed asynchronously, and may or may not be finished at any given point in time.
 *
 * From the perspective of dealing with error handling, deferred and promise APIs are to
 * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
 *
 * ```js
 *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
 *   // are available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     var deferred = $q.defer();
 *
 *     setTimeout(function() {
 *       deferred.notify('About to greet ' + name + '.');
 *
 *       if (okToGreet(name)) {
 *         deferred.resolve('Hello, ' + name + '!');
 *       } else {
 *         deferred.reject('Greeting ' + name + ' is not allowed.');
 *       }
 *     }, 1000);
 *
 *     return deferred.promise;
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   }, function(update) {
 *     alert('Got notification: ' + update);
 *   });
 * ```
 *
 * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
 * comes in the way of guarantees that promise and deferred APIs make, see
 * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
 *
 * Additionally the promise api allows for composition that is very hard to do with the
 * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
 * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
 * section on serial or parallel joining of promises.
 *
 * # The Deferred API
 *
 * A new instance of deferred is constructed by calling `$q.defer()`.
 *
 * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
 * that can be used for signaling the successful or unsuccessful completion, as well as the status
 * of the task.
 *
 * **Methods**
 *
 * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
 *   constructed via `$q.reject`, the promise will be rejected instead.
 * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
 *   resolving it with a rejection constructed via `$q.reject`.
 * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
 *   multiple times before the promise is either resolved or rejected.
 *
 * **Properties**
 *
 * - promise – `{Promise}` – promise object associated with this deferred.
 *
 *
 * # The Promise API
 *
 * A new promise instance is created when a deferred instance is created and can be retrieved by
 * calling `deferred.promise`.
 *
 * The purpose of the promise object is to allow for interested parties to get access to the result
 * of the deferred task when it completes.
 *
 * **Methods**
 *
 * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
 *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
 *   as soon as the result is available. The callbacks are called with a single argument: the result
 *   or rejection reason. Additionally, the notify callback may be called zero or more times to
 *   provide a progress indication, before the promise is resolved or rejected.
 *
 *   This method *returns a new promise* which is resolved or rejected via the return value of the
 *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
 *   with the value which is resolved in that promise using
 *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
 *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
 *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
 *   arguments are optional.
 *
 * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
 *
 * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
 *   but to do so without modifying the final value. This is useful to release resources or do some
 *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
 *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
 *   more information.
 *
 * # Chaining promises
 *
 * Because calling the `then` method of a promise returns a new derived promise, it is easily
 * possible to create a chain of promises:
 *
 * ```js
 *   promiseB = promiseA.then(function(result) {
 *     return result + 1;
 *   });
 *
 *   // promiseB will be resolved immediately after promiseA is resolved and its value
 *   // will be the result of promiseA incremented by 1
 * ```
 *
 * It is possible to create chains of any length and since a promise can be resolved with another
 * promise (which will defer its resolution further), it is possible to pause/defer resolution of
 * the promises at any point in the chain. This makes it possible to implement powerful APIs like
 * $http's response interceptors.
 *
 *
 * # Differences between Kris Kowal's Q and $q
 *
 *  There are two main differences:
 *
 * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
 *   mechanism in angular, which means faster propagation of resolution or rejection into your
 *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
 * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
 *   all the important functionality needed for common async tasks.
 *
 * # Testing
 *
 *  ```js
 *    it('should simulate promise', inject(function($q, $rootScope) {
 *      var deferred = $q.defer();
 *      var promise = deferred.promise;
 *      var resolvedValue;
 *
 *      promise.then(function(value) { resolvedValue = value; });
 *      expect(resolvedValue).toBeUndefined();
 *
 *      // Simulate resolving of promise
 *      deferred.resolve(123);
 *      // Note that the 'then' function does not get called synchronously.
 *      // This is because we want the promise API to always be async, whether or not
 *      // it got called synchronously or asynchronously.
 *      expect(resolvedValue).toBeUndefined();
 *
 *      // Propagate promise resolution to 'then' functions using $apply().
 *      $rootScope.$apply();
 *      expect(resolvedValue).toEqual(123);
 *    }));
 *  ```
 *
 * @param {function(function, function)} resolver Function which is responsible for resolving or
 *   rejecting the newly created promise. The first parameter is a function which resolves the
 *   promise, the second parameter is a function which rejects the promise.
 *
 * @returns {Promise} The newly created promise.

/**
 * DESIGN NOTES
 *
 * The design decisions behind the scope are heavily favored for speed and memory consumption.
 *
 * The typical use of scope is to watch the expressions, which most of the time return the same
 * value as last time so we optimize the operation.
 *
 * Closures construction is expensive in terms of speed as well as memory:
 *   - No closures, instead use prototypical inheritance for API
 *   - Internal state needs to be stored on scope directly, which means that private state is
 *     exposed as $$____ properties
 *
 * Loop operations are optimized by using while(count--) { ... }
 *   - This means that in order to keep the same order of execution as addition we have to add
 *     items to the array at the beginning (unshift) instead of at the end (push)
 *
 * Child scopes are created and removed often
 *   - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
 *
 * There are fewer watches than observers. This is why you don't want the observer to be implemented
 * in the same way as watch. Watch requires return of the initialization function which is expensive
 * to construct.

       * @description
       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
       *
       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
       *   its value when executed multiple times with the same input because it may be executed multiple
       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).
       * - The `listener` is called only when the value from the current `watchExpression` and the
       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
       *   see below). Inequality is determined according to reference inequality,
       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
       *    via the `!==` Javascript operator, unless `objectEquality == true`
       *   (see next point)
       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
       *   according to the {@link angular.equals} function. To save the value of the object for
       *   later comparison, the {@link angular.copy} function is used. This therefore means that
       *   watching complex objects will have adverse memory and performance implications.
       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
       *   iteration limit is 10 to prevent an infinite loop deadlock.
       *
       *
       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
       * you can register a `watchExpression` function with no `listener`. (Be prepared for
       * multiple calls to your `watchExpression` because it will execute multiple times in a
       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
       *
       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
       * watcher. In rare cases, this is undesirable because the listener is called when the result
       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
       * listener was called due to initialization.
       *
       *
       *
       * # Example
       * ```js
           // let's assume that scope was dependency injected as the $rootScope

       * - The `listener` is called whenever anything within the `obj` has changed. Examples include
       *   adding, removing, and moving items belonging to an object or array.

       * # Example

       *    {@link ng.$rootScope.Scope#$digest $digest} cycle. Any shallow change within the
       *    collection will trigger a call to the `listener`.
       *
       * @param {function(newCollection, oldCollection, scope)} listener a callback function called
       *    when a change is detected.
       *    - The `newCollection` object is the newly modified data obtained from the `obj` expression
       *    - The `oldCollection` object is a copy of the former collection data.
       *      Due to performance considerations, the`oldCollection` value is computed only if the
       *      `listener` function declares two or more arguments.
       *    - The `scope` argument refers to the current scope.

       *
       * @description
       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
       * until no more listeners are firing. This means that it is possible to get into an infinite
       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
       * iterations exceeds 10.
       *
       * Usually, you don't call `$digest()` directly in
       * {@link ng.directive:ngController controllers} or in
       * {@link ng.$compileProvider#directive directives}.
       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
       *
       * If you want to be notified whenever `$digest()` is called,
       * you can register a `watchExpression` function with
       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
       *
       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
       *
       * # Example
       * ```js
           var scope = ...;
           scope.name = 'misko';
           scope.counter = 0;

           expect(scope.counter).toEqual(0);

 * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict

 *
 * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
 * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
 * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to

 * work because `$sce` delegates to `$sceDelegate` for these operations.
 *
 * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
 *
 * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
 * can override it completely to change the behavior of `$sce`, the common case would
 * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
 * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
 * templates.  Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist

 *
 * @description
 *
 * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
 *
 * # Strict Contextual Escaping
 *
 * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
 * contexts to result in a value that is marked as safe to use for that context.  One example of
 * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
 * to these contexts as privileged or SCE contexts.
 *
 * As of version 1.2, Angular ships with SCE enabled by default.
 *
 * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
 * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
 * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
 * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
 * to the top of your HTML document.
 *
 * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
 * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
 *
 * Here's an example of a binding in a privileged context:
 *
 * ```
 * <input ng-model="userHtml" aria-label="User input">
 * <div ng-bind-html="userHtml"></div>
 * ```
 *
 * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
 * disabled, this application allows the user to render arbitrary HTML into the DIV.
 * In a more realistic example, one may be rendering user comments, blog articles, etc. via
 * bindings.  (HTML is just one example of a context where rendering user controlled input creates
 * security vulnerabilities.)
 *
 * For the case of HTML, you might use a library, either on the client side, or on the server side,
 * to sanitize unsafe HTML before binding to the value and rendering it in the document.
 *
 * How would you ensure that every place that used these types of bindings was bound to a value that
 * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
 * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
 * properties/fields and forgot to update the binding to the sanitized value?
 *
 * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
 * determine that something explicitly says it's safe to use a value for binding in that
 * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
 * for those values that you can easily tell are safe - because they were received from your server,
 * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
 * allowing only the files in a specific directory to do this.  Ensuring that the internal API
 * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
 *
 * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
 * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
 * obtain values that will be accepted by SCE / privileged contexts.
 *
 *
 * ## How does it work?
 *
 * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
 * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
 * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
 * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
 *
 * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
 * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
 * simplified):
 *
 * ```
 * var ngBindHtmlDirective = ['$sce', function($sce) {
 *   return function(scope, element, attr) {
 *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
 *       element.html(value || '');
 *     });
 *   };
 * }];
 * ```
 *
 * ## Impact on loading templates
 *
 * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
 * `templateUrl`'s specified by {@link guide/directive directives}.
 *
 * By default, Angular only loads templates from the same domain and protocol as the application
 * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
 * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
 * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
 * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
 *
 * *Please note*:
 * The browser's
 * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
 * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
 * policy apply in addition to this and may further restrict whether the template is successfully
 * loaded.  This means that without the right CORS policy, loading templates from a different domain
 * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
 * browsers.
 *
 * ## This feels like too much overhead
 *
 * It's important to remember that SCE only applies to interpolation expressions.
 *
 * If your expressions are constant literals, they're automatically trusted and you don't need to
 * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
 * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
 *
 * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
 * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
 *
 * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
 * templates in `ng-include` from your application's domain without having to even know about SCE.
 * It blocks loading templates from other domains or loading templates over http from an https
 * served document.  You can change these by setting your own custom {@link
 * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
 * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
 *
 * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
 * application that's secure and can be audited to verify that with much more ease than bolting
 * security onto an application later.
 *
 * <a name="contexts"></a>
 * ## What trusted context types are supported?
 *
 * | Context             | Notes          |
 * |---------------------|----------------|
 * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
 * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
 * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
 * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
 * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
 *
 * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
 *
 *  Each element in these arrays must be one of the following:
 *
 *  - **'self'**
 *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
 *      domain** as the application document using the **same protocol**.
 *  - **String** (except the special value `'self'`)
 *    - The string is matched against the full *normalized / absolute URL* of the resource
 *      being tested (substring matches are not good enough.)
 *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
 *      match themselves.
 *    - `*`: matches zero or more occurrences of any character other than one of the following 6
 *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
 *      in a whitelist.
 *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
 *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
 *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
 *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
 *      http://foo.example.com/templates/**).
 *  - **RegExp** (*see caveat below*)
 *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
 *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
 *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
 *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
 *      small number of cases.  A `.` character in the regex used when matching the scheme or a
 *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
 *      is highly recommended to use the string patterns and only fall back to regular expressions
 *      as a last resort.
 *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
 *      matched against the **entire** *normalized / absolute URL* of the resource being tested
 *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
 *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
 *    - If you are generating your JavaScript from some other templating engine (not
 *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
 *      remember to escape your regular expression (and be aware that you might need more than
 *      one level of escaping depending on your templating engine and the way you interpolated
 *      the value.)  Do make use of your platform's escaping mechanism as it might be good
 *      enough before coding your own.  E.g. Ruby has
 *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
 *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
 *      Javascript lacks a similar built in function for escaping.  Take a look at Google
 *      Closure library's [goog.string.regExpEscape(s)](
 *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
 *
 * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

 * ## Can I disable SCE completely?
 *
 * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
 * for little coding overhead.  It will be much harder to take an SCE disabled application and
 * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
 * for cases where you have a lot of existing code that was written before SCE was introduced and
 * you're migrating them a module at a time.
 *
 * That said, here's how you can completely disable SCE:
 *
 * ```
 * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
 *   // Completely disable SCE.  For demonstration purposes only!
 *   // Do not use in new projects.
 *   $sceProvider.enabled(false);
 * });
 * ```

  /* Design notes on the default implementation for SCE.
   *
   * The API contract for the SCE delegate
   * -------------------------------------
   * The SCE delegate object must provide the following 3 methods:
   *
   * - trustAs(contextEnum, value)
   *     This method is used to tell the SCE service that the provided value is OK to use in the
   *     contexts specified by contextEnum.  It must return an object that will be accepted by
   *     getTrusted() for a compatible contextEnum and return this value.
   *
   * - valueOf(value)
   *     For values that were not produced by trustAs(), return them as is.  For values that were
   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
   *     such a value.
   *
   * - getTrusted(contextEnum, value)
   *     This function should return the a value that is safe to use in the context specified by
   *     contextEnum or throw and exception otherwise.
   *
   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
   * instance, an implementation could maintain a registry of all trusted objects by context.  In
   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
   * return the same object passed in if it was found in the registry under a compatible context or
   * throw an exception otherwise.  An implementation might only wrap values some of the time based
   * on some criteria.  getTrusted() might return a value and not throw an exception for special
   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
   *
   *
   * A note on the inheritance model for SCE contexts
   * ------------------------------------------------
   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
   * is purely an implementation details.
   *
   * The contract is simply this:
   *
   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
   *     will also succeed.
   *
   * Inheritance happens to capture this in a natural way.  In some future, we
   * may not use inheritance anymore.  That is OK because no code outside of
   * sce.js and sceSpecs.js would need to be aware of this detail.

/**
 *
 * Implementation Notes for non-IE browsers
 * ----------------------------------------
 * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
 * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
 * URL will be resolved into an absolute URL in the context of the application document.
 * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
 * properties are all populated to reflect the normalized URL.  This approach has wide
 * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
 * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
 *
 * Implementation Notes for IE
 * ---------------------------
 * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
 * browsers.  However, the parsed components will not be set if the URL assigned did not specify
 * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
 * work around that by performing the parsing in a 2nd step by taking a previously normalized
 * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
 * properties such as protocol, hostname, port, etc.

/**

 * @description
 * A reference to the browser's `window` object. While `window`
 * is globally available in JavaScript, it causes testability problems, because
 * it is a global variable. In angular we always refer to it through the
 * `$window` service, so it may be overridden, removed or mocked for testing.
 *
 * Expressions, like the one defined for the `ngClick` directive in the example
 * below, are evaluated with respect to the current scope.  Therefore, there is
 * no risk of inadvertently coding in a dependency on a global value in such an
 * expression.

/**
 * @ngdoc filter
 * @name filter
 * @kind function
 *
 * @description
 * Selects a subset of items from `array` and returns it as a new array.
 *
 * @param {Array} array The source array.
 * @param {string|Object|function()} expression The predicate to be used for selecting items from
 *   `array`.
 *
 *   Can be one of:
 *
 *   - `string`: The string is used for matching against the contents of the `array`. All strings or
 *     objects with string properties in `array` that match this string will be returned. This also
 *     applies to nested object properties.
 *     The predicate can be negated by prefixing the string with `!`.
 *
 *   - `Object`: A pattern object can be used to filter specific properties on objects contained
 *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
 *     which have property `name` containing "M" and property `phone` containing "1". A special
 *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
 *     against any property of the object or its nested object properties. That's equivalent to the
 *     simple substring match with a `string` as described above. The special property name can be
 *     overwritten, using the `anyPropertyKey` parameter.
 *     The predicate can be negated by prefixing the string with `!`.
 *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
 *     not containing "M".
 *
 *     Note that a named property will match properties on the same level only, while the special
 *     `$` property will match properties on the same level or deeper. E.g. an array item like
 *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
 *     **will** be matched by `{$: 'John'}`.
 *
 *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
 *     The function is called for each element of the array, with the element, its index, and
 *     the entire array itself as arguments.
 *
 *     The final result is an array of those elements that the predicate returned true for.
 *
 * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
 *     determining if the expected value (from the filter expression) and actual value (from
 *     the object in the array) should be considered a match.
 *
 *   Can be one of:
 *
 *   - `function(actual, expected)`:
 *     The function will be given the object value and the predicate value to compare and
 *     should return true if both values should be considered equal.
 *
 *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
 *     This is essentially strict comparison of expected and actual.
 *
 *   - `false|undefined`: A short hand for a function which will look for a substring match in case
 *     insensitive way.
 *
 *     Primitive values are converted to strings. Objects are not compared against primitives,
 *     unless they have a custom `toString` method (e.g. `Date` objects).
 *
 * @param {string=} anyPropertyKey The special property name that matches against any property.
 *     By default `$`.
 *

 *
 * @description
 *   Formats `date` to a string based on the requested `format`.
 *
 *   `format` string can be composed of the following elements:
 *
 *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
 *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
 *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
 *   * `'MMMM'`: Month in year (January-December)
 *   * `'MMM'`: Month in year (Jan-Dec)
 *   * `'MM'`: Month in year, padded (01-12)
 *   * `'M'`: Month in year (1-12)
 *   * `'LLLL'`: Stand-alone month in year (January-December)
 *   * `'dd'`: Day in month, padded (01-31)
 *   * `'d'`: Day in month (1-31)
 *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
 *   * `'EEE'`: Day in Week, (Sun-Sat)
 *   * `'HH'`: Hour in day, padded (00-23)
 *   * `'H'`: Hour in day (0-23)
 *   * `'hh'`: Hour in AM/PM, padded (01-12)
 *   * `'h'`: Hour in AM/PM, (1-12)
 *   * `'mm'`: Minute in hour, padded (00-59)
 *   * `'m'`: Minute in hour (0-59)
 *   * `'ss'`: Second in minute, padded (00-59)
 *   * `'s'`: Second in minute (0-59)
 *   * `'sss'`: Millisecond in second, padded (000-999)
 *   * `'a'`: AM/PM marker
 *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
 *   * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
 *   * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
 *   * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
 *   * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
 *
 *   `format` string can also be one of the following predefined
 *   {@link guide/i18n localizable formats}:
 *
 *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
 *     (e.g. Sep 3, 2010 12:05:08 PM)
 *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 PM)
 *   * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US  locale
 *     (e.g. Friday, September 3, 2010)
 *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
 *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
 *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
 *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
 *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
 *
 *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
 *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
 *   (e.g. `"h 'o''clock'"`).
 *
 * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
 *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
 *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
 *    specified in the string input, the time is considered to be in the local timezone.
 * @param {string=} format Formatting rules (see Description). If not specified,
 *    `mediumDate` is used.
 * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
 *    continental US time zone abbreviations, but for general use, use a time zone offset, for
 *    example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
 *    If not specified, the timezone of the browser will be used.
 * @returns {string} Formatted string or the input if input is not recognized as date/millis.

/**
 * @ngdoc filter
 * @name limitTo
 * @kind function
 *
 * @description
 * Creates a new array or string containing only a specified number of elements. The elements are
 * taken from either the beginning or the end of the source array, string or number, as specified by
 * the value and sign (positive or negative) of `limit`. Other array-like objects are also supported
 * (e.g. array subclasses, NodeLists, jqLite/jQuery collections etc). If a number is used as input,
 * it is converted to a string.
 *
 * @param {Array|ArrayLike|string|number} input - Array/array-like, string or number to be limited.
 * @param {string|number} limit - The length of the returned array or string. If the `limit` number
 *     is positive, `limit` number of items from the beginning of the source array/string are copied.
 *     If the number is negative, `limit` number  of items from the end of the source array/string
 *     are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
 *     the input will be returned unchanged.
 * @param {(string|number)=} begin - Index at which to begin limitation. As a negative index,
 *     `begin` indicates an offset from the end of `input`. Defaults to `0`.
 * @returns {Array|string} A new sub-array or substring of length `limit` or less if the input had
 *     less than `limit` elements.

/**
 * @ngdoc filter
 * @name orderBy
 * @kind function
 *
 * @description
 * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
 * function based on the values computed using the `expression` predicate.
 *
 * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
 * `[{id: 'bar'}, {id: 'foo'}]`.
 *
 * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
 * String, etc).
 *
 * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
 * for the preceeding one. The `expression` is evaluated against each item and the output is used
 * for comparing with other items.
 *
 * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
 * ascending order.
 *
 * The comparison is done using the `comparator` function. If none is specified, a default, built-in
 * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
 * strings alphabetically).
 *
 * ### Under the hood
 *
 * Ordering the specified `collection` happens in two phases:
 *
 * 1. All items are passed through the predicate (or predicates), and the returned values are saved
 *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
 *    through a predicate that extracts the value of the `label` property, would be transformed to:
 *    ```
 *    {
 *      value: 'foo',
 *      type: 'string',
 *      index: ...
 *    }
 *    ```
 * 2. The comparator function is used to sort the items, based on the derived values, types and
 *    indices.
 *
 * If you use a custom comparator, it will be called with pairs of objects of the form
 * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
 * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
 * second, or `1` otherwise.
 *
 * In order to ensure that the sorting will be deterministic across platforms, if none of the
 * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
 * dummy predicate that returns the item's index as `value`.
 * (If you are using a custom comparator, make sure it can handle this predicate as well.)
 *
 * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
 * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
 * it to the comparator. The following rules govern the conversion:
 *
 * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
 *    used instead.<br />
 *    (If the object has a `valueOf()` method that returns another object, then the returned object
 *    will be used in subsequent steps.)
 * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
 *    returns a primitive, its return value will be used instead.<br />
 *    (If the object has a `toString()` method that returns another object, then the returned object
 *    will be used in subsequent steps.)
 * 3. No conversion; the object itself is used.
 *
 * ### The default comparator
 *
 * The default, built-in comparator should be sufficient for most usecases. In short, it compares
 * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
 * using their index in the original collection, and sorts values of different types by type.
 *
 * More specifically, it follows these steps to determine the relative order of items:
 *
 * 1. If the compared values are of different types, compare the types themselves alphabetically.
 * 2. If both values are of type `string`, compare them alphabetically in a case- and
 *    locale-insensitive way.
 * 3. If both values are objects, compare their indices instead.
 * 4. Otherwise, return:
 *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
 *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
 *    -  `1`, otherwise.
 *
 * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
 *           saved as numbers and not strings.
 *
 * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
 * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
 *    predicates) to be used by the comparator to determine the order of elements.
 *
 *    Can be one of:
 *
 *    - `Function`: A getter function. This function will be called with each item as argument and
 *      the return value will be used for sorting.
 *    - `string`: An Angular expression. This expression will be evaluated against each item and the
 *      result will be used for sorting. For example, use `'label'` to sort by a property called
 *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
 *      property.<br />
 *      (The result of a constant expression is interpreted as a property name to be used for
 *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
 *      property called `special name`.)<br />
 *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
 *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
 *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
 *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
 *      relative order of two items, the next predicate is used as a tie-breaker.
 *
 * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
 *
 * @param {boolean=} reverse - If `true`, reverse the sorting order.
 * @param {(Function)=} comparator - The comparator function used to determine the relative order of
 *    value pairs. If omitted, the built-in comparator will be used.
 *
 * @returns {Array} - The sorted array.
 *
 *
 * @example
 * ### Ordering a table with `ngRepeat`
 *
 * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
 * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
 * it defaults to the built-in comparator.

 * ### Using `orderBy` inside a controller
 *
 * It is also possible to call the `orderBy` filter manually, by injecting `orderByFilter`, and
 * calling it with the desired parameters. (Alternatively, you could inject the `$filter` factory
 * and retrieve the `orderBy` filter with `$filter('orderBy')`.)

 * ### Using a custom comparator
 *
 * If you have very specific requirements about the way items are sorted, you can pass your own
 * comparator function. For example, you might need to compare some strings in a locale-sensitive
 * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
 * argument - passing `false` retains the default sorting order, i.e. ascending.)

 * # Alias: {@link ng.directive:ngForm `ngForm`}
 *
 * In Angular, forms can be nested. This means that the outer form is valid when all of the child
 * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
 * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
 * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
 * of controls needs to be determined.
 *
 * # CSS classes
 *  - `ng-valid` is set if the form is valid.
 *  - `ng-invalid` is set if the form is invalid.
 *  - `ng-pending` is set if the form is pending.
 *  - `ng-pristine` is set if the form is pristine.
 *  - `ng-dirty` is set if the form is dirty.
 *  - `ng-submitted` is set if the form was submitted.
 *
 * Keep in mind that ngAnimate can detect each of these classes when added and removed.
 *
 *
 * # Submitting a form and preventing the default action
 *
 * Since the role of forms in client-side Angular applications is different than in classical
 * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
 * page reload that sends the data to the server. Instead some javascript logic should be triggered
 * to handle the form submission in an application-specific way.
 *
 * For this reason, Angular prevents the default action (form submission to the server) unless the
 * `<form>` element has an `action` attribute specified.
 *
 * You can use one of the following two ways to specify what javascript method should be called when
 * a form is submitted:
 *
 * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
 * - {@link ng.directive:ngClick ngClick} directive on the first
  *  button or input field of type submit (input[type=submit])
 *
 * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
 * or {@link ng.directive:ngClick ngClick} directives.
 * This is because of the following form submission rules in the HTML specification:
 *
 * - If a form has only one input field then hitting enter in this field triggers form submit
 * (`ngSubmit`)
 * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
 * doesn't trigger submit
 * - if a form has one or more input fields and one or more buttons or input[type=submit] then
 * hitting enter in any of the input fields will trigger the click handler on the *first* button or
 * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
 *
 * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
 * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
 * to have access to the updated model.
 *
 * ## Animation Hooks
 *
 * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
 * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
 * other validations that are performed within the form. Animations in ngForm are similar to how
 * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
 * as JS animations.
 *
 * The following example shows a simple way to utilize CSS transitions to style a form element
 * that has been rendered as invalid after it has been validated:
 *
 * <pre>
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-form {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-form.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * </pre>
 *
 * @example
    <example deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
      <file name="index.html">
       <script>
         angular.module('formExample', [])

          transition:all linear 0.5s;
          background: transparent;

   * @ngdoc input
   * @name input[text]
   *
   * @description
   * Standard HTML text input with angular data binding, inherited by most of the `input` elements.
   *
   *
   * @param {string} ngModel Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} required Adds `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
   *    `required` when you want to data-bind to the `required` attribute.
   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
   *    minlength.
   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
   *    any length.
   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
   *    that contains the regular expression body that will be converted to a regular expression
   *    as in the ngPattern directive.
   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
   *    If the expression evaluates to a RegExp object, then this is used directly.
   *    If the expression evaluates to a string, then it will be converted to a RegExp
   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
   *    `new RegExp('^abc$')`.<br />
   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
   *    start at the index of the last search's match, thus not taking the whole input value into
   *    account.
   * @param {string=} ngChange Angular expression to be executed when input changes due to user
   *    interaction with the input element.
   * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
   *    This parameter is ignored for input[type=password] controls, which will never trim the
   *    input.

  /**
   * @ngdoc input
   * @name input[number]
   *
   * @description
   * Text input with number validation and transformation. Sets the `number` validation
   * error if not a valid number.
   *
   * <div class="alert alert-warning">
   * The model must always be of type `number` otherwise Angular will throw an error.
   * Be aware that a string containing a number is not enough. See the {@link ngModel:numfmt}
   * error docs for more information and an example of how to convert your model if necessary.

   * ## Issues with HTML5 constraint validation
   *
   * In browsers that follow the
   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
   * If a non-number is entered in the input, the browser will report the value as an empty string,
   * which means the view / model values in `ngModel` and subsequently the scope value
   * will also be an empty string.
   *
   *
   * @param {string} ngModel Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
   * @param {string=} required Sets `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
   *    `required` when you want to data-bind to the `required` attribute.
   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
   *    minlength.
   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
   *    any length.
   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
   *    that contains the regular expression body that will be converted to a regular expression
   *    as in the ngPattern directive.
   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
   *    If the expression evaluates to a RegExp object, then this is used directly.
   *    If the expression evaluates to a string, then it will be converted to a RegExp
   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
   *    `new RegExp('^abc$')`.<br />
   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
   *    start at the index of the last search's match, thus not taking the whole input value into
   *    account.

 * Support for `select` models with non-string values is available via `ngOptions`.

 * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element

 * expression changes.
 *
 * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
 * `{{ expression }}` which is similar but less verbose.
 *
 * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
 * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
 * element attribute, it makes the bindings invisible to the user while the page is loading.
 *
 * An alternative solution to this problem would be using the
 * {@link ng.directive:ngCloak ngCloak} directive.
 *
 *

 * Enter a name in the Live Preview text box; the greeting below the text box changes instantly.

/**
 * @ngdoc directive
 * @name ngClass
 * @restrict AC
 *
 * @description
 * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
 * an expression that represents all classes to be added.
 *
 * The directive operates in three different ways, depending on which of three types the expression
 * evaluates to:
 *
 * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
 * names.
 *
 * 2. If the expression evaluates to an object, then for each key-value pair of the
 * object with a truthy value the corresponding key is used as a class name.
 *
 * 3. If the expression evaluates to an array, each element of the array should either be a string as in
 * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
 * to give you more control over what CSS classes appear. See the code below for an example of this.
 *
 *
 * The directive won't add duplicate classes if a particular class was already set.
 *
 * When the expression changes, the previously added classes are removed and only then are the
 * new classes added.
 *
 * @knownIssue

      <br>
      <span class="base-class" ng-class="myVar">Sample Text</span>
     </file>
     <file name="style.css">
       .base-class {
         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
       }

       .base-class.my-class {
         color: red;
         font-size:3em;
       }
     </file>
     <file name="protractor.js" type="protractor">
       it('should check ng-class', function() {
         expect(element(by.css('.base-class')).getAttribute('class')).not.
           toMatch(/my-class/);

         element(by.id('setbtn')).click();

         expect(element(by.css('.base-class')).getAttribute('class')).
           toMatch(/my-class/);

         element(by.id('clearbtn')).click();

         expect(element(by.css('.base-class')).getAttribute('class')).not.
           toMatch(/my-class/);
       });
     </file>
   </example>


   ## ngClass and pre-existing CSS3 Transitions/Animations
   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
   to view the step by step details of {@link $animate#addClass $animate.addClass} and
   {@link $animate#removeClass $animate.removeClass}.

 * @name ngCloak
 * @restrict AC
 *
 * @description
 * The `ngCloak` directive is used to prevent the Angular html template from being briefly
 * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
 * directive to avoid the undesirable flicker effect caused by the html template display.
 *
 * The directive can be applied to the `<body>` element, but the preferred usage is to apply
 * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
 * of the browser view.
 *
 * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
 * `angular.min.js`.
 * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
 *
 * ```css
 * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
 *   display: none !important;
 * }
 * ```
 *
 * When this css rule is loaded by the browser, all html elements (including their children) that
 * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
 * during the compilation of the template it deletes the `ngCloak` element attribute, making
 * the compiled element visible.
 *
 * For the best result, the `angular.js` script must be loaded in the head section of the html
 * document; alternatively, the css rule above must be included in the external stylesheet of the
 * application.
 *

 *
 * @example
   <example>

/**
 * @ngdoc directive
 * @name ngController
 *
 * @description
 * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
 * supports the principles behind the Model-View-Controller design pattern.
 *
 * MVC components in angular:
 *
 * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
 *   are accessed through bindings.
 * * View — The template (HTML with data bindings) that is rendered into the View.
 * * Controller — The `ngController` directive specifies a Controller class; the class contains business
 *   logic behind the application to decorate the scope with functions and values
 *
 * Note that you can also attach controllers to the DOM by declaring it in a route definition
 * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
 * again using `ng-controller` in the template itself.  This will cause the controller to be attached
 * and executed twice.
 *
 * @element ANY
 * @scope
 * @priority 500
 * @param {expression} ngController Name of a constructor function registered with the current
 * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
 * that on the current scope evaluates to a constructor function.
 *
 * The controller instance can be published into a scope property by specifying
 * `ng-controller="as propertyName"`.
 *
 * If the current `$controllerProvider` is configured to use globals (via
 * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
 * also be the name of a globally accessible constructor function (not recommended).
 *
 * @example
 * Here is a simple form for editing user contact information. Adding, removing, clearing, and
 * greeting are methods declared on the controller (see source tab). These methods can
 * easily be called from the angular markup. Any changes to the data are automatically reflected
 * in the View without the need for a manual update.
 *
 * Two different declaration styles are included below:
 *
 * * one binds methods and properties directly onto the controller using `this`:
 * `ng-controller="SettingsController1 as settings"`
 * * one injects `$scope` into the controller:
 * `ng-controller="SettingsController2"`
 *
 * The second option is more common in the Angular community, and is generally used in boilerplates
 * and in this guide. However, there are advantages to binding properties directly to the controller
 * and avoiding scope.
 *
 * * Using `controller as` makes it obvious which controller you are accessing in the template when
 * multiple controllers apply to an element.
 * * If you are writing your controllers as classes you have easier access to the properties and
 * methods, which will appear on the scope, from inside the controller code.
 * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
 * inheritance masking primitives.
 *
 * This example demonstrates the `controller as` syntax.

 * <example name="ngControllerAs" module="controllerAsExample">
 *   <file name="index.html">

 * (among other things). Angular makes use of this in the {@link $parse} service to provide a 30%
 * increase in the speed of evaluating Angular expressions.
 *
 * * `unsafe-inline`: this rule forbids apps from inject custom styles into the document. Angular
 * makes use of this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}).
 * To make these directives work when a CSP rule is blocking inline styles, you must link to the
 * `angular-csp.css` in your HTML manually.
 *
 * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking unsafe-eval
 * and automatically deactivates this feature in the {@link $parse} service. This autodetection,
 * however, triggers a CSP error to be logged in the console:
 *
 * ```
 * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
 * script in the following Content Security Policy directive: "default-src 'self'". Note that
 * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
 * ```
 *
 * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
 * directive on an element of the HTML document that appears before the `<script>` tag that loads
 * the `angular.js` file.
 *
 * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
 *
 * You can specify which of the CSP related Angular features should be deactivated by providing
 * a value for the `ng-csp` attribute. The options are as follows:
 *
 * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
 *
 * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
 *
 * You can use these values in the following combinations:
 *
 *
 * * No declaration means that Angular will assume that you can do inline styles, but it will do
 * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous versions
 * of Angular.
 *
 * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
 * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous versions
 * of Angular.
 *
 * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can inject
 * inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
 *
 * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
 * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
 *
 * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
 * styles nor use eval, which is the same as an empty: ng-csp.
 * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
 *
 * @example
 * This example shows how to apply the `ngCsp` directive to the `html` tag.
   ```html
     <!doctype html>
     <html ng-app ng-csp>
     ...
     ...
     </html>

/**
 * @ngdoc directive
 * @name ngIf
 * @restrict A
 * @multiElement
 *
 * @description
 * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
 * {expression}. If the expression assigned to `ngIf` evaluates to a false
 * value then the element is removed from the DOM, otherwise a clone of the
 * element is reinserted into the DOM.
 *
 * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
 * element in the DOM rather than changing its visibility via the `display` css property.  A common
 * case when this difference is significant is when using css selectors that rely on an element's
 * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
 *
 * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
 * is created when the element is restored.  The scope created within `ngIf` inherits from
 * its parent scope using
 * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
 * An important implication of this is if `ngModel` is used within `ngIf` to bind to
 * a javascript primitive defined in the parent scope. In this case any modifications made to the
 * variable within the child scope will override (hide) the value in the parent scope.
 *
 * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
 * is if an element's class attribute is directly modified after it's compiled, using something like
 * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
 * the added class will be lost because the original compiled state is used to regenerate the element.
 *
 * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
 * and `leave` effects.
 *
 * @animations
 * | Animation                        | Occurs                               |
 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
 * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
 *
 * @element ANY
 * @scope
 * @priority 600
 * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
 *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
 *     element is added to the DOM tree.
 *
 * @example
  <example module="ngAnimate" deps="angular-animate.js" animations="true">
    <file name="index.html">

/**
 * @ngdoc directive
 * @name ngList
 *
 * @description
 * Text input that converts between a delimited string and an array of strings. The default
 * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
 * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
 *
 * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
 * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
 *   list item is respected. This implies that the user of the directive is responsible for
 *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
 *   tab or newline character.
 * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
 *   when joining the list items back together) and whitespace around each list item is stripped
 *   before it is added to the model.

 * is set.
 * @property {*} $modelValue The value in the model that the control is bound to.
 * @property {Array.<Function>} $parsers Array of functions to execute, as a pipeline, whenever
       the control reads value from the DOM. The functions are called in array order, each passing

       {@link ngModel.NgModelController#$validators `$validators`} collection.

Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
`$viewValue`}.

Returning `undefined` from a parser means a parse error occurred. In that case,
no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
is set to `true`. The parse error is stored in `ngModel.$error.parse`.

 *
 * @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
       the model value changes. The functions are called in reverse array order, each passing the value through to the
       next. The last return value is used as the actual DOM value.
       Used to format / convert values for display in the control.
 * ```js

 *     return value.toUpperCase();
 *   }
 * }
 * ngModel.$formatters.push(formatter);
 * ```
 *
 * @property {Object.<string, function>} $validators A collection of validators that are applied
 *      whenever the model value changes. The key value within the object refers to the name of the
 *      validator while the function refers to the validation operation. The validation operation is
 *      provided with the model value as an argument and must return a true or false value depending
 *      on the response of that validation.
 *
 * ```js
 * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
 *   var value = modelValue || viewValue;
 *   return /[0-9]+/.test(value) &&
 *          /[a-z]+/.test(value) &&

 * };
 * ```
 *
 * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
 *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
 *      is expected to return a promise when it is run during the model validation process. Once the promise
 *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
 *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
 *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
 *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
 *      will only run once all synchronous validators have passed.
 *
 * Please note that if $http is used then it is important that the server returns a success HTTP response code
 * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
 *
 * ```js
 * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
 *   var value = modelValue || viewValue;
 *
 *   // Lookup user by username
 *   return $http.get('/api/users/' + value).

 * ```
 *
 * @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever the
 *     view value has changed. It is called with no arguments, and its return value is ignored.
 *     This can be used in place of additional $watches against the model value.
 *
 * @property {Object} $error An object hash with all failing validator ids as keys.

 * @description
 *
 * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
 * The controller contains services for data-binding, validation, CSS updates, and value formatting
 * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
 * listening to DOM events.
 * Such DOM related logic should be provided by other directives which make use of
 * `NgModelController` for data-binding to control elements.
 * Angular provides this DOM logic for most {@link input `input`} elements.
 * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
 * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
 *
 * @example
 * ### Custom Control Example
 * This example shows how to use `NgModelController` with a custom control to achieve
 * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
 * collaborate together to achieve the desired result.
 *
 * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
 * contents be edited in place by the user.
 *
 * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
 * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
 * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
 * that content using the `$sce` service.
 *
 * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
    <file name="style.css">
      [contenteditable] {
        border: 1px solid black;
        background-color: white;
        min-height: 20px;
      }

   *
   * @description
   * Update the view value.
   *
   * This method should be called when a control wants to change the view value; typically,
   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
   * directive calls it when the value of the input changes and {@link ng.directive:select select}
   * calls it when an option is selected.
   *
   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
   * value sent directly for processing, finally to be applied to `$modelValue` and then the
   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
   * in the `$viewChangeListeners` list, are called.
   *
   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
   * and the `default` trigger is not listed, all those actions will remain pending until one of the
   * `updateOn` events is triggered on the DOM element.
   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
   * directive is used with a custom debounce for this particular event.
   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
   * is specified, once the timer runs out.
   *
   * When used with standard inputs, the view value will always be a string (which is in some cases
   * parsed into another type, such as a `Date` object for `input[date]`.)
   * However, custom controls might also pass objects to this method. In this case, we should make
   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
   * perform a deep watch of objects, it only looks for a change of identity. If you only change
   * the property of the object then ngModel will not realize that the object has changed and
   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
   * not change properties of the copy once it has been passed to `$setViewValue`.
   * Otherwise you may cause the model value on the scope to change incorrectly.
   *
   * <div class="alert alert-info">
   * In any case, the value passed to the method should always reflect the current value
   * of the control. For example, if you are calling `$setViewValue` for an input element,
   * you should pass the input DOM value. Otherwise, the control and the scope model become
   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
   * the control's DOM value in any way. If we want to change the control's DOM value
   * programmatically, we should update the `ngModel` scope expression. Its new value will be
   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
   * to update the DOM, and finally call `$validate` on it.

/**
 * @ngdoc directive
 * @name ngModel
 *
 * @element input
 * @priority 1
 *
 * @description
 * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
 * property on the scope using {@link ngModel.NgModelController NgModelController},
 * which is created and exposed by this directive.
 *
 * `ngModel` is responsible for:
 *
 * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
 *   require.
 * - Providing validation behavior (i.e. required, number, email, url).
 * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
 * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
 *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
 * - Registering the control with its parent {@link ng.directive:form form}.
 *
 * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
 * current scope. If the property doesn't already exist on this scope, it will be created
 * implicitly and added to the scope.
 *
 * For best practices on using `ngModel`, see:
 *
 *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
 *
 * For basic examples, how to use `ngModel`, see:
 *
 *  - {@link ng.directive:input input}
 *    - {@link input[text] text}
 *    - {@link input[checkbox] checkbox}
 *    - {@link input[radio] radio}
 *    - {@link input[number] number}
 *    - {@link input[email] email}
 *    - {@link input[url] url}
 *    - {@link input[date] date}
 *    - {@link input[datetime-local] datetime-local}
 *    - {@link input[time] time}
 *    - {@link input[month] month}
 *    - {@link input[week] week}
 *  - {@link ng.directive:select select}
 *  - {@link ng.directive:textarea textarea}
 *
 * # Complex Models (objects or collections)
 *
 * By default, `ngModel` watches the model by reference, not value. This is important to know when
 * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
 * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
 *
 * The model must be assigned an entirely new object or collection before a re-rendering will occur.
 *
 * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
 * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
 * if the select is given the `multiple` attribute.
 *
 * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
 * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
 * not trigger a re-rendering of the model.
 *
 * # CSS classes
 * The following CSS classes are added and removed on the associated input/select/textarea element
 * depending on the validity of the model.
 *
 *  - `ng-valid`: the model is valid
 *  - `ng-invalid`: the model is invalid
 *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
 *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
 *  - `ng-pristine`: the control hasn't been interacted with yet
 *  - `ng-dirty`: the control has been interacted with
 *  - `ng-touched`: the control has been blurred
 *  - `ng-untouched`: the control hasn't been blurred
 *  - `ng-pending`: any `$asyncValidators` are unfulfilled
 *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
 *     by the {@link ngModel.NgModelController#$isEmpty} method
 *  - `ng-not-empty`: the view contains a non-empty value
 *
 * Keep in mind that ngAnimate can detect each of these classes when added and removed.
 *
 * ## Animation Hooks
 *
 * Animations within models are triggered when any of the associated CSS classes are added and removed
 * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
 * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
 * The animations that are triggered within ngModel are similar to how they work in ngClass and
 * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
 *
 * The following example shows a simple way to utilize CSS transitions to style an input element
 * that has been rendered as invalid after it has been validated:
 *
 * <pre>
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-input {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-input.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * </pre>
 *
 * @example
 * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
     <file name="index.html">
       <script>
        angular.module('inputExample', [])
          .controller('ExampleController', ['$scope', function($scope) {
            $scope.val = '1';
          }]);
       </script>
       <style>
         .my-input {
           transition:all linear 0.5s;
           background: transparent;
         }
         .my-input.ng-invalid {
           color:white;
           background: red;
         }
       </style>
       <p id="inputDescription">
        Update input to see transitions when valid/invalid.
        Integer is a valid value.
       </p>
       <form name="testForm" ng-controller="ExampleController">
         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
                aria-describedby="inputDescription" />
       </form>
     </file>
 * </example>
 *
 * ## Binding to a getter/setter
 *
 * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
 * function that returns a representation of the model when called with zero arguments, and sets
 * the internal state of a model when called with an argument. It's sometimes useful to use this
 * for models that have an internal representation that's different from what the model exposes
 * to the view.
 *
 * <div class="alert alert-success">
 * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
 * frequently than other parts of your code.
 * </div>
 *
 * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
 * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
 * a `<form>`, which will enable this behavior for all `<input>`s within it. See
 * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.

/**
 * @ngdoc directive
 * @name ngModelOptions
 *
 * @description
 * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
 * events that will trigger a model update and/or a debouncing delay so that the actual update only
 * takes place when a timer expires; this timer will be reset after another change takes place.
 *
 * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
 * be different from the value in the actual model. This means that if you update the model you
 * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
 * order to make sure it is synchronized with the model and that any debounced action is canceled.
 *
 * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
 * method is by making sure the input is placed inside a form that has a `name` attribute. This is
 * important because `form` controllers are published to the related scope under the name in their
 * `name` attribute.
 *
 * Any pending changes will take place immediately when an enclosing form is submitted via the
 * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
 * to have access to the updated model.
 *
 * `ngModelOptions` has an effect on the element it's declared on and its descendants.
 *
 * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
 *   - `updateOn`: string specifying which event should the input be bound to. You can set several
 *     events using an space delimited list. There is a special event called `default` that
 *     matches the default events belonging of the control.
 *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
 *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
 *     custom value for each event. For example:
 *     `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
 *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
 *     not validate correctly instead of the default behavior of setting the model to undefined.
 *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
       `ngModel` as getters/setters.
 *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
 *     `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
 *     continental US time zone abbreviations, but for general use, use a time zone offset, for
 *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
 *     If not specified, the timezone of the browser will be used.
 *
 * @example

  The following example shows how to override immediate updates. Changes on the inputs within the
  form will update the model only when the control loses focus (blur event). If `escape` key is
  pressed while the input field is focused, the value is reset to the value in the current model.

  <example name="ngModelOptions-directive-blur" module="optionsExample">
    <file name="index.html">

  If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.

/**
 * @ngdoc directive
 * @name ngOptions
 * @restrict A
 *
 * @description
 *
 * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
 * elements for the `<select>` element using the array or object obtained by evaluating the
 * `ngOptions` comprehension expression.
 *
 * In many cases, `ngRepeat` can be used on `<option>` elements instead of `ngOptions` to achieve a
 * similar result. However, `ngOptions` provides some benefits such as reducing memory and
 * increasing speed by not creating a new scope for each repeated instance, as well as providing
 * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
 * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
 *  to a non-string value. This is because an option element can only be bound to string values at
 * present.
 *
 * When an item in the `<select>` menu is selected, the array element or object property
 * represented by the selected option will be bound to the model identified by the `ngModel`
 * directive.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
 * option. See example below for demonstration.
 *
 * ## Complex Models (objects or collections)
 *
 * By default, `ngModel` watches the model by reference, not value. This is important to know when
 * binding the select to a model that is an object or a collection.
 *
 * One issue occurs if you want to preselect an option. For example, if you set
 * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
 * because the objects are not identical. So by default, you should always reference the item in your collection
 * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
 *
 * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
 * of the item not by reference, but by the result of the `track by` expression. For example, if your
 * collection items have an id property, you would `track by item.id`.
 *
 * A different issue with objects or collections is that ngModel won't detect if an object property or
 * a collection item changes. For that reason, `ngOptions` additionally watches the model using
 * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
 * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
 * has not changed identity, but only a property on the object or an item in the collection changes.
 *
 * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
 * if the model is an array). This means that changing a property deeper than the first level inside the
 * object/collection will not trigger a re-rendering.
 *
 * ## `select` **`as`**
 *
 * Using `select` **`as`** will bind the result of the `select` expression to the model, but
 * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
 * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
 * is used, the result of that expression will be set as the value of the `option` and `select` elements.
 *
 *
 * ### `select` **`as`** and **`track by`**
 *
 * <div class="alert alert-warning">
 * Be careful when using `select` **`as`** and **`track by`** in the same expression.
 * </div>
 *
 * Given this array of items on the $scope:
 *
 * ```js
 * $scope.items = [{
 *   id: 1,
 *   label: 'aLabel',
 *   subItem: { name: 'aSubItem' }
 * }, {
 *   id: 2,
 *   label: 'bLabel',
 *   subItem: { name: 'bSubItem' }
 * }];
 * ```
 *
 * This will work:
 *
 * ```html
 * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
 * ```
 * ```js
 * $scope.selected = $scope.items[0];
 * ```
 *
 * but this will not work:
 *
 * ```html
 * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
 * ```
 * ```js
 * $scope.selected = $scope.items[0].subItem;
 * ```
 *
 * In both examples, the **`track by`** expression is applied successfully to each `item` in the
 * `items` array. Because the selected option has been set programmatically in the controller, the
 * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
 * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
 * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
 * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
 * is not matched against any `<option>` and the `<select>` appears as having no selected value.
 *
 *
 * @param {string} ngModel Assignable angular expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} required The control is considered valid only if value is entered.
 * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
 *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
 *    `required` when you want to data-bind to the `required` attribute.
 * @param {comprehension_expression=} ngOptions in one of the following forms:
 *
 *   * for array data sources:
 *     * `label` **`for`** `value` **`in`** `array`
 *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
 *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
 *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
 *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
 *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
 *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
 *        (for including a filter with `track by`)
 *   * for object data sources:

 *
 *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
 *   * `value`: local variable which will refer to each item in the `array` or each property value
 *      of `object` during iteration.
 *   * `key`: local variable which will refer to a property name in `object` during iteration.
 *   * `label`: The result of this expression will be the label for `<option>` element. The
 *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
 *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
 *      element. If not specified, `select` expression will default to `value`.
 *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
 *      DOM element.
 *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
 *      element. Return `true` to disable.
 *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
 *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
 *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
 *      even when the options are recreated (e.g. reloaded from the server).

/**
 * @ngdoc directive
 * @name ngPluralize
 * @restrict EA
 *
 * @description
 * `ngPluralize` is a directive that displays messages according to en-US localization rules.
 * These rules are bundled with angular.js, but can be overridden
 * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
 * by specifying the mappings between
 * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
 * and the strings to be displayed.
 *
 * # Plural categories and explicit number rules
 * There are two
 * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
 * in Angular's default en-US locale: "one" and "other".
 *
 * While a plural category may match many numbers (for example, in en-US locale, "other" can match
 * any number that is not 1), an explicit number rule can only match one number. For example, the
 * explicit number rule for "3" matches the number 3. There are examples of plural categories
 * and explicit number rules throughout the rest of this documentation.
 *
 * # Configuring ngPluralize
 * You configure ngPluralize by providing 2 attributes: `count` and `when`.
 * You can also provide an optional attribute, `offset`.
 *
 * The value of the `count` attribute can be either a string or an {@link guide/expression
 * Angular expression}; these are evaluated on the current scope for its bound value.
 *
 * The `when` attribute specifies the mappings between plural categories and the actual
 * string to be displayed. The value of the attribute should be a JSON object.
 *
 * The following example shows how to configure ngPluralize:
 *
 * ```html
 * <ng-pluralize count="personCount"
                 when="{'0': 'Nobody is viewing.',
 *                      'one': '1 person is viewing.',
 *                      'other': '{} people are viewing.'}">
 * </ng-pluralize>
 *```
 *
 * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
 * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
 * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
 * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
 * show "a dozen people are viewing".
 *
 * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
 * into pluralized strings. In the previous example, Angular will replace `{}` with
 * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
 * for <span ng-non-bindable>{{numberExpression}}</span>.
 *
 * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
 * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
 *
 * # Configuring ngPluralize with offset
 * The `offset` attribute allows further customization of pluralized text, which can result in
 * a better user experience. For example, instead of the message "4 people are viewing this document",
 * you might display "John, Kate and 2 others are viewing this document".
 * The offset attribute allows you to offset a number by any desired value.
 * Let's take a look at an example:
 *
 * ```html
 * <ng-pluralize count="personCount" offset=2
 *               when="{'0': 'Nobody is viewing.',
 *                      '1': '{{person1}} is viewing.',
 *                      '2': '{{person1}} and {{person2}} are viewing.',
 *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
 *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
 * </ng-pluralize>
 * ```
 *
 * Notice that we are still using two plural categories(one, other), but we added
 * three explicit number rules 0, 1 and 2.
 * When one person, perhaps John, views the document, "John is viewing" will be shown.
 * When three people view the document, no explicit number rule is found, so
 * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
 * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
 * is shown.
 *
 * Note that when you specify offsets, you must provide explicit number rules for
 * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
 * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
 * plural categories "one" and "other".
 *
 * @param {string|expression} count The variable to be bound to.
 * @param {string} when The mapping between plural category to its corresponding strings.
 * @param {number=} offset Offset to deduct from the total number.
 *

 * The `ngRepeat` directive instantiates a template once per item from a collection. Each template

 * and `$index` is set to the item index or key.
 *
 * Special properties are exposed on the local scope of each template instance, including:
 *
 * | Variable  | Type            | Details                                                                     |

 * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
 * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |

 *
 * <div class="alert alert-info">
 *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
 *   This may be useful when, for instance, nesting ngRepeats.
 * </div>
 *
 *
 * # Iterating over object properties
 *
 * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
 * syntax:
 *
 * ```js
 * <div ng-repeat="(key, value) in myObj"> ... </div>
 * ```
 *
 * However, there are a limitations compared to array iteration:
 *
 * - The JavaScript specification does not define the order of keys
 *   returned for an object, so Angular relies on the order returned by the browser
 *   when running `for key in myObj`. Browsers generally follow the strategy of providing
 *   keys in the order in which they were defined, although there are exceptions when keys are deleted
 *   and reinstated. See the
 *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
 *
 * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
 *   it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
 *
 * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
 *   objects, and will throw an error if used with one.
 *
 * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
 * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
 * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
 * or implement a `$watch` on the object yourself.
 *
 *
 * # Tracking and Duplicates
 *
 * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
 * the collection. When a change happens, ngRepeat then makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * To minimize creation of DOM elements, `ngRepeat` uses a function
 * to "keep track" of all items in the collection and their corresponding DOM elements.
 * For example, if an item is added to the collection, ngRepeat will know that all other items
 * already have DOM elements, and will not re-render them.
 *
 * The default tracking function (which tracks items by their identity) does not allow
 * duplicate items in arrays. This is because when there are duplicates, it is not possible
 * to maintain a one-to-one mapping between collection items and DOM elements.
 *
 * If you do need to repeat duplicate items, you can substitute the default tracking behavior
 * with your own using the `track by` expression.
 *
 * For example, you may track items by the index of each item in the collection, using the
 * special scope property `$index`:
 * ```html
 *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
 *      {{n}}
 *    </div>
 * ```
 *
 * You may also use arbitrary expressions in `track by`, including references to custom functions
 * on the scope:
 * ```html
 *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
 *      {{n}}
 *    </div>
 * ```
 *
 * <div class="alert alert-success">
 * If you are working with objects that have an identifier property, you should track
 * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`
 * will not have to rebuild the DOM elements for items it has already rendered, even if the
 * JavaScript objects in the collection have been substituted for new ones. For large collections,
 * this significantly improves rendering performance. If you don't have a unique identifier,
 * `track by $index` can also provide a performance boost.
 * </div>
 * ```html
 *    <div ng-repeat="model in collection track by model.id">
 *      {{model.name}}
 *    </div>
 * ```
 *
 * When no `track by` expression is provided, it is equivalent to tracking by the built-in
 * `$id` function, which tracks items by their identity:
 * ```html
 *    <div ng-repeat="obj in collection track by $id(obj)">
 *      {{obj.prop}}
 *    </div>
 * ```
 *
 * <div class="alert alert-warning">
 * **Note:** `track by` must always be the last expression:
 * </div>
 * ```
 * <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
 *     {{model.name}}
 * </div>
 * ```
 *
 * # Special repeat start and end points
 * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
 * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
 * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
 * up to and including the ending HTML tag where **ng-repeat-end** is placed.
 *
 * The example below makes use of this feature:
 * ```html
 *   <header ng-repeat-start="item in items">
 *     Header {{ item }}
 *   </header>
 *   <div class="body">
 *     Body {{ item }}
 *   </div>
 *   <footer ng-repeat-end>
 *     Footer {{ item }}
 *   </footer>
 * ```
 *
 * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
 * ```html
 *   <header>
 *     Header A
 *   </header>
 *   <div class="body">
 *     Body A
 *   </div>
 *   <footer>
 *     Footer A
 *   </footer>
 *   <header>
 *     Header B
 *   </header>
 *   <div class="body">
 *     Body B
 *   </div>
 *   <footer>
 *     Footer B
 *   </footer>
 * ```
 *
 * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
 * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
 * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
 * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
 *
 * See the example below for defining CSS animations with ngRepeat.
 *
 * @element ANY
 * @scope
 * @priority 1000
 * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
 *   formats are currently supported:
 *
 *   * `variable in expression` – where variable is the user defined loop variable and `expression`
 *     is a scope expression giving the collection to enumerate.
 *
 *     For example: `album in artist.albums`.
 *
 *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
 *     and `expression` is the scope expression giving the collection to enumerate.
 *
 *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
 *
 *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
 *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
 *     is specified, ng-repeat associates elements by identity. It is an error to have
 *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
 *     mapped to the same DOM element, which is not possible.)
 *
 *     Note that the tracking expression must come last, after any filters, and the alias expression.
 *
 *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
 *     will be associated by item identity in the array.
 *
 *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
 *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
 *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
 *     element in the same way in the DOM.
 *
 *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
 *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
 *     property is same.
 *
 *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
 *     to items in conjunction with a tracking expression.
 *
 *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
 *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
 *     when a filter is active on the repeater, but the filtered result set is empty.
 *
 *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
 *     the items have been processed through the filter.
 *
 *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
 *     (and not as operator, inside an expression).
 *
 *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
 *
 * @example
 * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
 * results by name. New (entering) and removed (leaving) items are animated.

/**
 * @ngdoc directive
 * @name ngShow
 * @multiElement
 *
 * @description
 * The `ngShow` directive shows or hides the given HTML element based on the expression
 * provided to the `ngShow` attribute. The element is shown or hidden by removing or adding
 * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
 * in AngularJS and sets the display style to none (using an !important flag).
 * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
 *
 * ```html
 * <!-- when $scope.myValue is truthy (element is visible) -->
 * <div ng-show="myValue"></div>
 *
 * <!-- when $scope.myValue is falsy (element is hidden) -->
 * <div ng-show="myValue" class="ng-hide"></div>
 * ```
 *
 * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class
 * attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed
 * from the element causing the element not to appear hidden.
 *
 * ## Why is !important used?
 *
 * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
 * can be easily overridden by heavier selectors. For example, something as simple
 * as changing the display style on a HTML list item would make hidden elements appear visible.
 * This also becomes a bigger issue when dealing with CSS frameworks.
 *
 * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
 * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
 * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
 *
 * ### Overriding `.ng-hide`
 *
 * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
 * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
 * class CSS. Note that the selector that needs to be used is actually `.ng-hide:not(.ng-hide-animate)` to cope
 * with extra animation classes that can be added.
 *
 * ```css
 * .ng-hide:not(.ng-hide-animate) {
 *   /&#42; this is just another form of hiding an element &#42;/
 *   display: block!important;
 *   position: absolute;
 *   top: -9999px;
 *   left: -9999px;
 * }
 * ```
 *
 * By default you don't need to override in CSS anything and the animations will work around the display style.
 *
 * ## A note about animations with `ngShow`
 *
 * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
 * is true and false. This system works like the animation system present with ngClass except that
 * you must also include the !important flag to override the display property
 * so that you can perform an animation when the element is hidden during the time of the animation.
 *
 * ```css
 * //
 * //a working example can be found at the bottom of this page
 * //
 * .my-element.ng-hide-add, .my-element.ng-hide-remove {
 *   /&#42; this is required as of 1.3x to properly
 *      apply all styling in a show/hide animation &#42;/
 *   transition: 0s linear all;
 * }
 *
 * .my-element.ng-hide-add-active,
 * .my-element.ng-hide-remove-active {
 *   /&#42; the transition is defined in the active class &#42;/
 *   transition: 1s linear all;
 * }
 *
 * .my-element.ng-hide-add { ... }
 * .my-element.ng-hide-add.ng-hide-add-active { ... }
 * .my-element.ng-hide-remove { ... }
 * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
 * ```
 *
 * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display
 * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
 *

/**
 * @ngdoc directive
 * @name ngHide
 * @multiElement
 *
 * @description
 * The `ngHide` directive shows or hides the given HTML element based on the expression
 * provided to the `ngHide` attribute. The element is shown or hidden by removing or adding
 * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
 * in AngularJS and sets the display style to none (using an !important flag).
 * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
 *
 * ```html
 * <!-- when $scope.myValue is truthy (element is hidden) -->
 * <div ng-hide="myValue" class="ng-hide"></div>
 *
 * <!-- when $scope.myValue is falsy (element is visible) -->
 * <div ng-hide="myValue"></div>
 * ```
 *
 * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added to the class
 * attribute on the element causing it to become hidden. When falsy, the `.ng-hide` CSS class is removed
 * from the element causing the element not to appear hidden.
 *
 * ## Why is !important used?
 *
 * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
 * can be easily overridden by heavier selectors. For example, something as simple
 * as changing the display style on a HTML list item would make hidden elements appear visible.
 * This also becomes a bigger issue when dealing with CSS frameworks.
 *
 * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
 * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
 * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
 *
 * ### Overriding `.ng-hide`
 *
 * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
 * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
 * class in CSS:
 *
 * ```css
 * .ng-hide {
 *   /&#42; this is just another form of hiding an element &#42;/
 *   display: block!important;
 *   position: absolute;
 *   top: -9999px;
 *   left: -9999px;
 * }
 * ```
 *
 * By default you don't need to override in CSS anything and the animations will work around the display style.
 *
 * ## A note about animations with `ngHide`
 *
 * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
 * is true and false. This system works like the animation system present with ngClass, except that the `.ng-hide`
 * CSS class is added and removed for you instead of your own CSS class.
 *
 * ```css
 * //
 * //a working example can be found at the bottom of this page
 * //
 * .my-element.ng-hide-add, .my-element.ng-hide-remove {
 *   transition: 0.5s linear all;
 * }
 *
 * .my-element.ng-hide-add { ... }
 * .my-element.ng-hide-add.ng-hide-add-active { ... }
 * .my-element.ng-hide-remove { ... }
 * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
 * ```
 *
 * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display
 * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
 *

/**
 * @ngdoc directive

 * @description
 * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
 * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
 * as specified in the template.
 *
 * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
 * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
 * matches the value obtained from the evaluated expression. In other words, you define a container element
 * (where you place the directive), place an expression on the **`on="..."` attribute**
 * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
 * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
 * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
 * attribute is displayed.
 *
 * <div class="alert alert-info">
 * Be aware that the attribute values to match against cannot be expressions. They are interpreted
 * as literal string values to match against.
 * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
 * value of the expression `$scope.someVal`.
 * </div>

 * | {@link ng.$animate#leave leave}  | after the ngSwitch contents change and just before the former contents are removed from the DOM |

 * @param {*} ngSwitch|on expression to match against <code>ng-switch-when</code>.
 * On child elements add:

 * * `ngSwitchWhen`: the case statement to match against. If match then this
 *   case will be displayed. If the same match appears multiple times, all the
 *   elements will be displayed.
 * * `ngSwitchDefault`: the default case when no other case match. If there
 *   are multiple default cases, all of them will be displayed when no other

/**
 * @ngdoc directive
 * @name select
 * @restrict E
 *
 * @description
 * HTML `SELECT` element with angular data-binding.
 *
 * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
 * between the scope and the `<select>` control (including setting default values).
 * It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
 * {@link ngOptions `ngOptions`} directives.
 *
 * When an item in the `<select>` menu is selected, the value of the selected option will be bound
 * to the model identified by the `ngModel` directive. With static or repeated options, this is
 * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
 * If you want dynamic value attributes, you can use interpolation inside the value attribute.
 *
 * <div class="alert alert-warning">
 * Note that the value of a `select` directive used without `ngOptions` is always a string.
 * When the model needs to be bound to a non-string value, you must either explicitly convert it
 * using a directive (see example below) or use `ngOptions` to specify the set of options.
 * This is because an option element can only be bound to string values at present.
 * </div>
 *
 * If the viewValue of `ngModel` does not match any of the options, then the control
 * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
 * option. See example below for demonstration.
 *
 * <div class="alert alert-info">
 * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
 * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits, such as
 * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
 * comprehension expression, and additionally in reducing memory and increasing speed by not creating
 * a new scope for each repeated instance.
 * </div>
 *
 *
 * @param {string} ngModel Assignable angular expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} multiple Allows multiple options to be selected. The selected values will be
 *     bound to the model as an array.
 * @param {string=} required Sets `required` validation error key if the value is not entered.
 * @param {string=} ngRequired Adds required attribute and required validation constraint to
 * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
 * when you want to data-bind to the required attribute.
 * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
 *    interaction with the select element.
 * @param {string=} ngOptions sets the options that the select is populated with and defines what is
 * set on the model on selection. See {@link ngOptions `ngOptions`}.

/**
 * @ngdoc directive
 * @name ngRequired
 * @restrict A
 *
 * @description
 *
 * ngRequired adds the required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
 * It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be
 * applied to custom controls.
 *
 * The directive sets the `required` attribute on the element if the Angular expression inside
 * `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we
 * cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}
 * for more info.
 *
 * The validator will set the `required` error key to true if the `required` attribute is set and
 * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
 * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
 * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
 * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.
 *
 * @example
 * <example name="ngRequiredDirective" module="ngRequiredExample">
 *   <file name="index.html">
 *     <script>
 *       angular.module('ngRequiredExample', [])

 * ngPattern adds the pattern {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
 * It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.
 *
 * The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
 * does not match a RegExp which is obtained by evaluating the Angular expression given in the

 * * If the expression evaluates to a RegExp object, then this is used directly.
 * * If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it
 * in `^` and `$` characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`.
 *
 * <div class="alert alert-info">
 * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

/**
 * @ngdoc service
 * @name $resource
 * @requires $http
 * @requires ng.$log
 * @requires $q
 * @requires ng.$timeout
 *
 * @description
 * A factory which creates a resource object that lets you interact with
 * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
 *
 * The returned resource object has action methods which provide high-level behaviors without
 * the need to interact with the low level {@link ng.$http $http} service.
 *
 * Requires the {@link ngResource `ngResource`} module to be installed.
 *
 * By default, trailing slashes will be stripped from the calculated URLs,
 * which can pose problems with server backends that do not expect that
 * behavior.  This can be disabled by configuring the `$resourceProvider` like
 * this:
 *
 * ```js
     app.config(['$resourceProvider', function($resourceProvider) {
       // Don't strip trailing slashes from calculated URLs
       $resourceProvider.defaults.stripTrailingSlashes = false;
     }]);
 * ```
 *
 * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
 *   `/user/:username`. If you are using a URL with a port number (e.g.
 *   `http://example.com:8080/api`), it will be respected.
 *
 *   If you are using a url with a suffix, just add the suffix, like this:
 *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
 *   or even `$resource('http://example.com/resource/:resource_id.:format')`
 *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
 *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
 *   can escape it with `/\.`.
 *
 * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
 *   `actions` methods. If a parameter value is a function, it will be called every time
 *   a param value needs to be obtained for a request (unless the param was overridden). The function
 *   will be passed the current data value as an argument.
 *
 *   Each key value in the parameter object is first bound to url template if present and then any
 *   excess keys are appended to the url search query after the `?`.
 *
 *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
 *   URL `/path/greet?salutation=Hello`.
 *
 *   If the parameter value is prefixed with `@`, then the value for that parameter will be
 *   extracted from the corresponding property on the `data` object (provided when calling a
 *   "non-GET" action method).
 *   For example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of
 *   `someParam` will be `data.someProp`.
 *   Note that the parameter will be ignored, when calling a "GET" action method (i.e. an action
 *   method that does not accept a request body)
 *
 * @param {Object.<Object>=} actions Hash with declaration of custom actions that should extend
 *   the default set of resource actions. The declaration should be created in the format of {@link
 *   ng.$http#usage $http.config}:
 *
 *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
 *        action2: {method:?, params:?, isArray:?, headers:?, ...},
 *        ...}
 *
 *   Where:
 *
 *   - **`action`** – {string} – The name of action. This name becomes the name of the method on
 *     your resource object.
 *   - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
 *     `DELETE`, `JSONP`, etc).
 *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
 *     the parameter value is a function, it will be called every time when a param value needs to
 *     be obtained for a request (unless the param was overridden). The function will be passed the
 *     current data value as an argument.
 *   - **`url`** – {string} – action specific `url` override. The url templating is supported just
 *     like for the resource-level urls.
 *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
 *     see `returns` section.
 *   - **`transformRequest`** –
 *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
 *     transform function or an array of such functions. The transform function takes the http
 *     request body and headers and returns its transformed (typically serialized) version.
 *     By default, transformRequest will contain one function that checks if the request data is
 *     an object and serializes to using `angular.toJson`. To prevent this behavior, set
 *     `transformRequest` to an empty array: `transformRequest: []`
 *   - **`transformResponse`** –
 *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
 *     transform function or an array of such functions. The transform function takes the http
 *     response body and headers and returns its transformed (typically deserialized) version.
 *     By default, transformResponse will contain one function that checks if the response looks
 *     like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,
 *     set `transformResponse` to an empty array: `transformResponse: []`
 *   - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
 *     GET request, otherwise if a cache instance built with
 *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
 *     caching.
 *   - **`timeout`** – `{number}` – timeout in milliseconds.<br />
 *     **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are
 *     **not** supported in $resource, because the same value would be used for multiple requests.
 *     If you are looking for a way to cancel requests, you should use the `cancellable` option.
 *   - **`cancellable`** – `{boolean}` – if set to true, the request made by a "non-instance" call
 *     will be cancelled (if not already completed) by calling `$cancelRequest()` on the call's
 *     return value. Calling `$cancelRequest()` for a non-cancellable or an already
 *     completed/cancelled request will have no effect.<br />
 *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
 *     XHR object. See
 *     [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
 *     for more information.
 *   - **`responseType`** - `{string}` - see
 *     [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
 *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
 *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
 *     with `http response` object. See {@link ng.$http $http interceptors}.
 *
 * @param {Object} options Hash with custom settings that should extend the
 *   default `$resourceProvider` behavior.  The supported options are:
 *
 *   - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
 *   slashes from any calculated URL will be stripped. (Defaults to true.)
 *   - **`cancellable`** – {boolean} – If true, the request made by a "non-instance" call will be
 *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.
 *   This can be overwritten per action. (Defaults to false.)
 *
 * @returns {Object} A resource "class" object with methods for the default set of resource actions
 *   optionally extended with custom `actions`. The default set contains these actions:
 *   ```js
 *   { 'get':    {method:'GET'},
 *     'save':   {method:'POST'},
 *     'query':  {method:'GET', isArray:true},
 *     'remove': {method:'DELETE'},
 *     'delete': {method:'DELETE'} };
 *   ```
 *
 *   Calling these methods invoke an {@link ng.$http} with the specified http method,
 *   destination and parameters. When the data is returned from the server then the object is an
 *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
 *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
 *   read, update, delete) on server-side data like this:
 *   ```js
 *   var User = $resource('/user/:userId', {userId:'@id'});
 *   var user = User.get({userId:123}, function() {
 *     user.abc = true;
 *     user.$save();
 *   });
 *   ```
 *
 *   It is important to realize that invoking a $resource object method immediately returns an
 *   empty reference (object or array depending on `isArray`). Once the data is returned from the
 *   server the existing reference is populated with the actual data. This is a useful trick since
 *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
 *   object results in no rendering, once the data arrives from the server then the object is
 *   populated with the data and the view automatically re-renders itself showing the new data. This
 *   means that in most cases one never has to write a callback function for the action methods.
 *
 *   The action methods on the class object or instance object can be invoked with the following
 *   parameters:
 *
 *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
 *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
 *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
 *
 *
 *   Success callback is called with (value, responseHeaders) arguments, where the value is
 *   the populated resource instance or collection object. The error callback is called
 *   with (httpResponse) argument.
 *
 *   Class actions return empty instance (with additional properties below).
 *   Instance actions return promise of the action.
 *
 *   The Resource instances and collections have these additional properties:
 *
 *   - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
 *     instance or collection.
 *
 *     On success, the promise is resolved with the same resource instance or collection object,
 *     updated with data from server. This makes it easy to use in
 *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
 *     rendering until the resource(s) are loaded.
 *
 *     On failure, the promise is rejected with the {@link ng.$http http response} object, without
 *     the `resource` property.
 *
 *     If an interceptor object was provided, the promise will instead be resolved with the value
 *     returned by the interceptor.
 *
 *   - `$resolved`: `true` after first server interaction is completed (either with success or
 *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
 *      data-binding.
 *
 *   The Resource instances and collections have these additional methods:
 *
 *   - `$cancelRequest`: If there is a cancellable, pending request related to the instance or
 *      collection, calling this method will abort the request.
 *
 *   The Resource instances have these additional methods:
 *
 *   - `toJSON`: It returns a simple object without any of the extra properties added as part of
 *     the Resource API. This object can be serialized through {@link angular.toJson} safely
 *     without attaching Angular-specific fields. Notice that `JSON.stringify` (and
 *     `angular.toJson`) automatically use this method when serializing a Resource instance
 *     (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON()_behavior)).
 *
 * @example
 *
 * # Credit card resource
 *
 * ```js
     // Define CreditCard class
     var CreditCard = $resource('/user/:userId/card/:cardId',
      {userId:123, cardId:'@id'}, {
       charge: {method:'POST', params:{charge:true}}
      });

     // We can retrieve a collection from the server
     var cards = CreditCard.query(function() {
       // GET: /user/123/card
       // server returns: [ {id:456, number:'1234', name:'Smith'} ];

       var card = cards[0];
       // each item is an instance of CreditCard
       expect(card instanceof CreditCard).toEqual(true);
       card.name = "J. Smith";
       // non GET methods are mapped onto the instances
       card.$save();
       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
       // server returns: {id:456, number:'1234', name: 'J. Smith'};

       // our custom method is mapped as well.
       card.$charge({amount:9.99});
       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
     });

     // we can create an instance as well
     var newCard = new CreditCard({number:'0123'});
     newCard.name = "Mike Smith";
     newCard.$save();
     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
     // server returns: {id:789, number:'0123', name: 'Mike Smith'};
     expect(newCard.id).toEqual(789);
 * ```
 *
 * The object returned from this function execution is a resource "class" which has "static" method
 * for each action in the definition.
 *
 * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
 * `headers`.
 *
 * @example
 *
 * # User resource
 *
 * When the data is returned from the server then the object is an instance of the resource type and
 * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
 * operations (create, read, update, delete) on server-side data.

   ```js
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(user) {
       user.abc = true;
       user.$save();
     });
   ```
 *
 * It's worth noting that the success callback for `get`, `query` and other methods gets passed
 * in the response that came from the server as well as $http header getter function, so one
 * could rewrite the above example and get access to http headers as:
 *
   ```js
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(user, getResponseHeaders){
       user.abc = true;
       user.$save(function(user, putResponseHeaders) {
         //user => saved user object
         //putResponseHeaders => $http header getter
       });
     });
   ```
 *
 * You can also access the raw `$http` promise via the `$promise` property on the object returned
 *
   ```
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123})
         .$promise.then(function(user) {
           $scope.user = user;
         });
   ```
 *
 * @example
 *
 * # Creating a custom 'PUT' request
 *
 * In this example we create a custom method on our resource to make a PUT request
 * ```js
 *    var app = angular.module('app', ['ngResource', 'ngRoute']);
 *
 *    // Some APIs expect a PUT request in the format URL/object/ID
 *    // Here we are creating an 'update' method
 *    app.factory('Notes', ['$resource', function($resource) {
 *    return $resource('/notes/:id', null,
 *        {
 *            'update': { method:'PUT' }
 *        });
 *    }]);
 *
 *    // In our controller we get the ID from the URL using ngRoute and $routeParams
 *    // We pass in $routeParams and our Notes factory along with $scope
 *    app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
                                      function($scope, $routeParams, Notes) {
 *    // First get a note object from the factory
 *    var note = Notes.get({ id:$routeParams.id });
 *    $id = note.id;
 *
 *    // Now call update passing in the ID first then the object you are updating
 *    Notes.update({ id:$id }, note);
 *
 *    // This will PUT /notes/ID with the note object in the request payload
 *    }]);
 * ```
 *
 * @example
 *
 * # Cancelling requests
 *
 * If an action's configuration specifies that it is cancellable, you can cancel the request related
 * to an instance or collection (as long as it is a result of a "non-instance" call):
 *
   ```js
     // ...defining the `Hotel` resource...
     var Hotel = $resource('/api/hotel/:id', {id: '@id'}, {
       // Let's make the `query()` method cancellable
       query: {method: 'get', isArray: true, cancellable: true}
     });

     // ...somewhere in the PlanVacationController...
     ...
     this.onDestinationChanged = function onDestinationChanged(destination) {
       // We don't care about any pending request for hotels
       // in a different destination any more
       this.availableHotels.$cancelRequest();

       // Let's query for hotels in '<destination>'
       // (calls: /api/hotel?location=<destination>)
       this.availableHotels = Hotel.query({location: destination});
     };
   ```

    /**
     * @ngdoc property
     * @name $resourceProvider#defaults
     * @description
     * Object containing default options used when creating `$resource` instances.
     *
     * The default values satisfy a wide range of usecases, but you may choose to overwrite any of
     * them to further customize your instances. The available properties are:
     *
     * - **stripTrailingSlashes** – `{boolean}` – If true, then the trailing slashes from any
     *   calculated URL will be stripped.<br />
     *   (Defaults to true.)
     * - **cancellable** – `{boolean}` – If true, the request made by a "non-instance" call will be
     *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
     *   value. For more details, see {@link ngResource.$resource}. This can be overwritten per
     *   resource class or action.<br />
     *   (Defaults to false.)
     * - **actions** - `{Object.<Object>}` - A hash with default actions declarations. Actions are
     *   high-level methods corresponding to RESTful actions/methods on resources. An action may
     *   specify what HTTP method to use, what URL to hit, if the return value will be a single
     *   object or a collection (array) of objects etc. For more details, see
     *   {@link ngResource.$resource}. The actions can also be enhanced or overwritten per resource
     *   class.<br />
     *   The default actions are:
     *   ```js
     *   {
     *     get: {method: 'GET'},
     *     save: {method: 'POST'},
     *     query: {method: 'GET', isArray: true},
     *     remove: {method: 'DELETE'},
     *     delete: {method: 'DELETE'}
     *   }
     *   ```
     *
     * #### Example
     *
     * For example, you can specify a new `update` action that uses the `PUT` HTTP verb:
     *
     * ```js
     *   angular.
     *     module('myApp').
     *     config(['resourceProvider', function ($resourceProvider) {
     *       $resourceProvider.defaults.actions.update = {
     *         method: 'PUT'
     *       };
     *     });
     * ```
     *
     * Or you can even overwrite the whole `actions` list and specify your own:
     *
     * ```js
     *   angular.
     *     module('myApp').
     *     config(['resourceProvider', function ($resourceProvider) {
     *       $resourceProvider.defaults.actions = {
     *         create: {method: 'POST'}
     *         get:    {method: 'GET'},
     *         getAll: {method: 'GET', isArray:true},
     *         update: {method: 'PUT'},
     *         delete: {method: 'DELETE'}
     *       };
     *     });
     * ```
     *

 * There are several sub-modules included with the ui.router module, however only this module is needed
 * as a dependency within your angular app. The other modules are for organization purposes. 
 *
 * The modules are:
 * * ui.router - the main "umbrella" module
 * * ui.router.router - 
 * 
 * *You'll need to include **only** this module as the dependency within your angular app.*

   * @ngdoc function
   * @name ui.router.util.$resolve#resolve
   * @methodOf ui.router.util.$resolve
   *
   * @description
   * Resolves a set of invocables. An invocable is a function to be invoked via 
   * `$injector.invoke()`, and can have an arbitrary number of dependencies. 
   * An invocable can either return a value directly,
   * or a `$q` promise. If a promise is returned it will be resolved and the 
   * resulting value will be used instead. Dependencies of invocables are resolved 
   * (in this order of precedence)
   *
   * - from the specified `locals`
   * - from another invocable that is part of this `$resolve` call
   * - from an invocable that is inherited from a `parent` call to `$resolve` 
   *   (or recursively
   * - from any ancestor `$resolve` of that parent).
   *
   * The return value of `$resolve` is a promise for an object that contains 
   * (in this order of precedence)
   *
   * - any `locals` (if specified)
   * - the resolved return values of all injectables
   * - any values inherited from a `parent` call to `$resolve` (if specified)
   *
   * The promise will resolve after the `parent` promise (if any) and all promises 
   * returned by injectables have been resolved. If any invocable 
   * (or `$injector.invoke`) throws an exception, or if a promise returned by an 
   * invocable is rejected, the `$resolve` promise is immediately rejected with the 
   * same error. A rejection of a `parent` promise (if specified) will likewise be 
   * propagated immediately. Once the `$resolve` promise has been rejected, no 
   * further invocables will be called.
   * 
   * Cyclic dependencies between invocables are not permitted and will cause `$resolve`
   * to throw an error. As a special case, an injectable can depend on a parameter 
   * with the same name as the injectable, which will be fulfilled from the `parent` 
   * injectable of the same name. This allows inherited values to be decorated. 
   * Note that in this case any other injectable in the same `$resolve` with the same
   * dependency would see the decorated value, not the inherited value.
   *
   * Note that missing dependencies -- unlike cyclic dependencies -- will cause an 
   * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous) 
   * exception.
   *
   * Invocables are invoked eagerly as soon as all dependencies are available. 
   * This is true even for dependencies inherited from a `parent` call to `$resolve`.
   *
   * As a special case, an invocable can be a string, in which case it is taken to 
   * be a service name to be passed to `$injector.get()`. This is supported primarily 
   * for backwards-compatibility with the `resolve` property of `$routeProvider` 
   * routes.
   *
   * @param {object} invocables functions to invoke or 
   * `$injector` services to fetch.
   * @param {object} locals  values to make available to the injectables
   * @param {object} parent  a promise returned by another call to `$resolve`.
   * @param {object} self  the `this` for the invoked methods
   * @return {object} Promise for an object that contains the resolved return value
   * of all invocables, as well as any inherited and local values.

/**
 * @ngdoc object
 * @name ui.router.util.type:UrlMatcher
 *
 * @description
 * Matches URLs against patterns and extracts named parameters from the path or the search
 * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
 * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
 * do not influence whether or not a URL is matched, but their values are passed through into
 * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
 *
 * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
 * syntax, which optionally allows a regular expression for the parameter to be specified:
 *
 * * `':'` name - colon placeholder
 * * `'*'` name - catch-all placeholder
 * * `'{' name '}'` - curly placeholder
 * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
 *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
 *
 * Parameter names may contain only word characters (latin letters, digits, and underscore) and
 * must be unique within the pattern (across both path and search parameters). For colon
 * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
 * number of characters other than '/'. For catch-all placeholders the path parameter matches
 * any number of characters.
 *
 * Examples:
 *
 * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
 *   trailing slashes, and patterns have to match the entire path, not just a prefix.
 * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
 *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
 * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
 * * `'/user/{id:[^/]*}'` - Same as the previous example.
 * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
 *   parameter consists of 1 to 8 hex digits.
 * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
 *   path into the parameter 'path'.
 * * `'/files/*path'` - ditto.
 * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
 *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
 *
 * @param {string} pattern  The pattern to compile into a matcher.
 * @param {Object} config  A configuration object hash:
 * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
 *   an existing UrlMatcher
 *
 * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
 * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
 *
 * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
 *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
 *   non-null) will start with this prefix.
 *
 * @property {string} source  The pattern that was passed into the constructor
 *
 * @property {string} sourcePath  The path portion of the source property
 *
 * @property {string} sourceSearch  The search portion of the source property
 *
 * @property {string} regex  The constructed regex that will be used to match against the url when
 *   it is time to determine which url will match.
 *
 * @returns {Object}  New `UrlMatcher` object

  /**
   * @ngdoc function
   * @name ui.router.state.$stateProvider#decorator
   * @methodOf ui.router.state.$stateProvider
   *
   * @description
   * Allows you to extend (carefully) or override (at your own peril) the 
   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
   * to add custom functionality to ui-router, for example inferring templateUrl 
   * based on the state name.
   *
   * When passing only a name, it returns the current (original or decorated) builder
   * function that matches `name`.
   *
   * The builder functions that can be decorated are listed below. Though not all
   * necessarily have a good use case for decoration, that is up to you to decide.
   *
   * In addition, users can attach custom decorators, which will generate new 
   * properties within the state's internal definition. There is currently no clear 
   * use-case for this beyond accessing internal states (i.e. $state.$current), 
   * however, expect this to become increasingly relevant as we introduce additional 
   * meta-programming features.
   *
   * **Warning**: Decorators should not be interdependent because the order of 
   * execution of the builder functions in non-deterministic. Builder functions 
   * should only be dependent on the state definition object and super function.
   *
   *
   * Existing builder functions and current return values:
   *
   * - **parent** `{object}` - returns the parent state object.
   * - **data** `{object}` - returns state data, including any inherited data that is not
   *   overridden by own values (if any).
   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
   *   or `null`.
   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
   *   navigable).
   * - **params** `{object}` - returns an array of state params that are ensured to 
   *   be a super-set of parent's params.
   * - **views** `{object}` - returns a views object where each key is an absolute view 
   *   name (i.e. "viewName@stateName") and each value is the config object 
   *   (template, controller) for the view. Even when you don't use the views object 
   *   explicitly on a state config, one is still created for you internally.
   *   So by decorating this builder function you have access to decorating template 
   *   and controller properties.
   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
   *   not including any params defined by ancestor states.
   * - **path** `{string}` - returns the full path from the root down to this state. 
   *   Needed for state activation.
   * - **includes** `{object}` - returns an object that includes every state that 
   *   would pass a `$state.includes()` test.
   *
   * @example
   * <pre>
   * // Override the internal 'views' builder with a function that takes the state
   * // definition, and a reference to the internal function being overridden:

   *       views = parent(state);

   *     result[name] = config;
   *   });
   *   return result;
   * });
   *

   *     it is injected and return value it treated as dependency. If result is a promise, it is 
   *     resolved before its value is injected into controller.

   *     }</pre>
   *
   * @param {string=} stateConfig.url
   * <a id='url'></a>
   *
   *   A url fragment with optional parameters. When a state is navigated or
   *   transitioned to, the `$stateParams` service will be populated with any 
   *   parameters that were passed.
   *
   *   (See {@link ui.router.util.type:UrlMatcher UrlMatcher} `UrlMatcher`} for
   *   more details on acceptable patterns )
   *
   * examples:
   * <pre>url: "/home"
   * url: "/users/:userid"
   * url: "/books/{bookid:[a-zA-Z_-]}"
   * url: "/books/{categoryid:int}"
   * url: "/books/{publishername:string}/{categoryid:int}"
   * url: "/messages?before&after"
   * url: "/messages?{before:date}&{after:date}"
   * url: "/messages/:mailboxid?{before:date}&{after:date}"
   * </pre>
   *
   * @param {object=} stateConfig.views
   * <a id='views'></a>
   * an optional map&lt;string, object&gt; which defined multiple views, or targets views
   * manually/explicitly.
   *
   * Examples:
   *
   * Targets three named `ui-view`s in the parent state's template
   * <pre>views: {
   *     header: {
   *       controller: "headerCtrl",
   *       templateUrl: "header.html"
   *     }, body: {
   *       controller: "bodyCtrl",
   *       templateUrl: "body.html"
   *     }, footer: {
   *       controller: "footCtrl",
   *       templateUrl: "footer.html"
   *     }
   *   }</pre>
   *
   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
   * <pre>views: {
   *     'header@top': {
   *       controller: "msgHeaderCtrl",
   *       templateUrl: "msgHeader.html"
   *     }, 'body': {
   *       controller: "messagesCtrl",
   *       templateUrl: "messages.html"
   *     }
   *   }</pre>
   *
   * @param {boolean=} [stateConfig.abstract=false]
   * <a id='abstract'></a>
   * An abstract state will never be directly activated,
   *   but can provide inherited properties to its common children states.
   * <pre>abstract: true</pre>
   *
   * @param {function=} stateConfig.onEnter
   * <a id='onEnter'></a>
   *
   * Callback function for when a state is entered. Good way
   *   to trigger an action or dispatch an event, such as opening a dialog.
   * If minifying your scripts, make sure to explicitly annotate this function,
   * because it won't be automatically annotated by your build tools.
   *
   * <pre>onEnter: function(MyService, $stateParams) {
   *     MyService.foo($stateParams.myParam);
   * }</pre>
   *
   * @param {function=} stateConfig.onExit
   * <a id='onExit'></a>
   *
   * Callback function for when a state is exited. Good way to
   *   trigger an action or dispatch an event, such as opening a dialog.
   * If minifying your scripts, make sure to explicitly annotate this function,
   * because it won't be automatically annotated by your build tools.
   *
   * <pre>onExit: function(MyService, $stateParams) {
   *     MyService.cleanup($stateParams.myParam);
   * }</pre>
   *
   * @param {boolean=} [stateConfig.reloadOnSearch=true]
   * <a id='reloadOnSearch'></a>
   *
   * If `false`, will not retrigger the same state
   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
   *   Useful for when you'd like to modify $location.search() without triggering a reload.
   * <pre>reloadOnSearch: false</pre>
   *
   * @param {object=} stateConfig.data
   * <a id='data'></a>
   *
   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
   *   prototypally inherited.  In other words, adding a data property to a state adds it to
   *   the entire subtree via prototypal inheritance.
   *
   * <pre>data: {
   *     requiredRole: 'foo'
   * } </pre>
   *
   * @param {object=} stateConfig.params
   * <a id='params'></a>
   *
   * A map which optionally configures parameters declared in the `url`, or
   *   defines additional non-url parameters.  For each parameter being
   *   configured, add a configuration object keyed to the name of the parameter.
   *
   *   Each parameter configuration object may contain the following properties:
   *
   *   - ** value ** - {object|function=}: specifies the default value for this
   *     parameter.  This implicitly sets this parameter as optional.
   *
   *     When UI-Router routes to a state and no value is
   *     specified for this parameter in the URL or transition, the
   *     default value will be used instead.  If `value` is a function,
   *     it will be injected and invoked, and the return value used.
   *
   *     *Note*: `undefined` is treated as "no default value" while `null`
   *     is treated as "the default value is `null`".
   *
   *     *Shorthand*: If you only need to configure the default value of the
   *     parameter, you may use a shorthand syntax.   In the **`params`**
   *     map, instead mapping the param name to a full parameter configuration
   *     object, simply set map it to the default parameter value, e.g.:
   *
   * <pre>// define a parameter's default value
   * params: {
   *     param1: { value: "defaultValue" }
   * }
   * // shorthand default values
   * params: {
   *     param1: "defaultValue",
   *     param2: "param2Default"
   * }</pre>
   *
   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
   *     treated as an array of values.  If you specified a Type, the value will be
   *     treated as an array of the specified Type.  Note: query parameter values
   *     default to a special `"auto"` mode.
   *
   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
   *     value (e.g.: `{ foo: '1' }`).
   *
   * <pre>params: {
   *     param1: { array: true }
   * }</pre>
   *
   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
   *     configured default squash policy.
   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
   *
   *   There are three squash settings:
   *
   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
   *       This can allow for cleaner looking URLs.
   *     - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
   *
   * <pre>params: {
   *     param1: {
   *       value: "defaultId",
   *       squash: true
   * } }
   * // squash "defaultValue" to "~"
   * params: {
   *     param1: {
   *       value: "defaultValue",
   *       squash: "~"
   * } }
   * </pre>
   *
   *
   * @example
   * <pre>
   * // Some state name examples
   *
   * // stateName can be a single top-level name (must be unique).
   * $stateProvider.state("home", {});
   *
   * // Or it can be a nested state name. This state is a child of the
   * // above "home" state.
   * $stateProvider.state("home.newest", {});
   *
   * // Nest states as deeply as needed.
   * $stateProvider.state("home.newest.abc.xyz.inception", {});
   *
   * // state() returns $stateProvider, so you can chain state declarations.
   * $stateProvider
   *   .state("home", {})
   *   .state("about", {})
   *   .state("contacts", {});

     * @description
     * Convenience method for transitioning to a new state. `$state.go` calls 
     * `$state.transitionTo` internally but automatically sets options to 
     * `{ location: true, inherit: true, relative: $state.$current, notify: true }`. 
     * This allows you to easily use an absolute or relative to path and specify 
     * only the parameters you'd like to update (while letting unspecified parameters 
     * inherit from the currently active ancestor states).
     *
     * @example
     * <pre>
     * var app = angular.module('app', ['ui.router']);
     *
     * app.controller('ctrl', function ($scope, $state) {

     * @param {string} to Absolute state name or relative state path. Some examples:
     *
     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
     * - `$state.go('^')` - will go to a parent state
     * - `$state.go('^.sibling')` - will go to a sibling state
     * - `$state.go('.child.grandchild')` - will go to grandchild state
     *
     * @param {object=} params A map of the parameters that will be sent to the state, 
     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
     * defined parameters. Only parameters specified in the state definition can be overridden, new 
     * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
     * will get you all current parameters, etc.
     * @param {object=} options Options object. The options are:
     *
     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
     *    defines which state to be relative from.
     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
     * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
     *    have changed.  It will reload the resolves and views of the current state and parent states.
     *    If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \
     *    the transition reloads the resolves and views for that matched state, and all its children states.
     *
     * @returns {promise} A promise representing the state of the new transition.
     *
     * Possible success values:
     *
     * - $state.current
     *
     * <br/>Possible rejection values:
     *
     * - 'transition superseded' - when a newer transition has been started after this one
     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
     *   when a `$stateNotFound` `event.retry` promise errors.

 * @requires $controller
 * @requires $injector
 * @requires ui.router.state.$uiViewScroll
 * @requires $document
 *
 * @restrict ECA
 *
 * @description
 * The ui-view directive tells $state where to place your templates.
 *
 * @param {string=} name A view name. The name should be unique amongst the other views in the
 * same state. You can have views of the same name that live in different states.
 *
 * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
 * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
 * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
 * scroll ui-view elements into view when they are populated during a state activation.
 *
 * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
 * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
 *
 * @param {string=} onload Expression to evaluate whenever the view updates.
 *
 * @example
 * A view can be unnamed or named.
 * <pre>
 * <!-- Unnamed -->
 * <div ui-view></div>
 *
 * <!-- Named -->
 * <div ui-view="viewName"></div>
 * </pre>
 *
 * You can only have one unnamed view within any template (or root html). If you are only using a
 * single view and it is unnamed then you can populate it like so:
 * <pre>
 * <div ui-view></div>
 * $stateProvider.state("home", {
 *   template: "<h1>HELLO!</h1>"
 * })
 * </pre>
 *
 * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#methods_state `views`}
 * config property, by name, in this case an empty name:
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * But typically you'll only use the views property if you name your view or have more than one view
 * in the same template. There's not really a compelling reason to name a view if its the only one,
 * but you could if you wanted, like so:
 * <pre>
 * <div ui-view="main"></div>
 * </pre>
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "main": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * Really though, you'll use views to set up multiple views:
 * <pre>
 * <div ui-view></div>
 * <div ui-view="chart"></div>
 * <div ui-view="data"></div>
 * </pre>
 *
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     },
 *     "chart": {
 *       template: "<chart_thing/>"
 *     },
 *     "data": {
 *       template: "<data_thing/>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * Examples for `autoscroll`:
 *
 * <pre>
 * <!-- If autoscroll present with no expression,
 *      then scroll ui-view into view -->
 * <ui-view autoscroll/>
 *
 * <!-- If autoscroll present with valid expression,
 *      then scroll ui-view into view if expression evaluates to true -->
 * <ui-view autoscroll='true'/>
 * <ui-view autoscroll='false'/>
 * <ui-view autoscroll='scopeVariable'/>
 * </pre>
 *
 * Resolve data:
 *
 * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
 * can be customized using [[ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
 *
 * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
 * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
 * depends on `$resolve` data.
 *
 * Example usage of $resolve in a view template
 * <pre>
 * $stateProvider.state('home', {
 *   template: '<my-component user="$resolve.user"></my-component>',
 *   resolve: {
 *     user: function(UserService) { return UserService.fetchUser(); }
 *   }
 * });
 * </pre>

 *
 * @description
 * A directive that binds a link (`<a>` tag) to a state. If the state has an associated
 * URL, the directive will automatically generate & update the `href` attribute via
 * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
 * the link will trigger a state transition with optional parameters.
 *
 * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
 * handled natively by the browser.
 *
 * You can also use relative state paths within ui-sref, just like the relative
 * paths passed to `$state.go()`. You just need to be aware that the path is relative
 * to the state that the link lives in, in other words the state that loaded the
 * template containing the link.
 *
 * You can specify options to pass to {@link ui.router.state.$state#methods_go $state.go()}
 * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
 * and `reload`.
 *
 * @example
 * Here's an example of how you'd use ui-sref and how it would compile. If you have the
 * following template:
 * <pre>
 * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
 *     </li>
 * </ul>
 * </pre>
 *
 * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
 * <pre>
 * <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
 *     </li>
 * </ul>
 *
 * <a ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
 * </pre>

 * @requires $interpolate
 *
 * @restrict A
 *
 * @description
 * A directive working alongside ui-sref to add classes to an element when the
 * related ui-sref directive's state is active, and removing them when it is inactive.
 * The primary use-case is to simplify the special appearance of navigation menus
 * relying on `ui-sref`, by having the "active" state's menu button appear different,
 * distinguishing it from the inactive menu items.
 *
 * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
 * ui-sref-active found at the same level or above the ui-sref will be used.
 *
 * Will activate when the ui-sref's target state or any child state is active. If you
 * need to activate only when the ui-sref target state is active and *not* any of
 * it's children, then you will use
 * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
 *
 * @example
 * Given the following template:
 * <pre>
 * <ul>
 *   <li ui-sref-active="active" class="item">
 *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
 *   </li>
 * </ul>
 * </pre>
 *
 *
 * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
 * the resulting HTML will appear as (note the 'active' class):
 * <pre>
 * <ul>
 *   <li ui-sref-active="active" class="item active">
 *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
 *   </li>
 * </ul>
 * </pre>
 *
 * The class name is interpolated **once** during the directives link time (any further changes to the
 * interpolated value are ignored).
 *
 * Multiple classes may be specified in a space-separated format:
 * <pre>
 * <ul>
 *   <li ui-sref-active='class1 class2 class3'>
 *     <a ui-sref="app.user">link</a>
 *   </li>
 * </ul>
 * </pre>
 *
 * It is also possible to pass ui-sref-active an expression that evaluates
 * to an object hash, whose keys represent active class names and whose
 * values represent the respective state names/globs.
 * ui-sref-active will match if the current active state **includes** any of
 * the specified state names/globs, even the abstract ones.
 *
 * @Example
 * Given the following template, with "admin" being an abstract state:
 * <pre>
 * <div ui-sref-active="{'active': 'admin.*'}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * </pre>
 *
 * When the current state is "admin.roles" the "active" class will be applied
 * to both the <div> and <a> elements. It is important to note that the state
 * names/globs passed to ui-sref-active shadow the state provided by ui-sref.

/**
 * @ngdoc module
 * @name ngMessages
 * @description
 *
 * The `ngMessages` module provides enhanced support for displaying messages within templates
 * (typically within forms or when rendering message objects that return key/value data).
 * Instead of relying on JavaScript code and/or complex ng-if statements within your form template to
 * show and hide error messages specific to the state of an input field, the `ngMessages` and
 * `ngMessage` directives are designed to handle the complexity, inheritance and priority
 * sequencing based on the order of how the messages are defined in the template.
 *
 * Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`
 * `ngMessage` and `ngMessageExp` directives.
 *
 * # Usage
 * The `ngMessages` directive allows keys in a key/value collection to be associated with a child element
 * (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use
 * case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the
 * {@link ngModel ngModel} directive.
 *
 * The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or
 * `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by
 * the `ngMessages` directive.
 *
 * Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we
 * have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}
 * directive.
 *
 * The `myField` field is a required input of type `email` with a maximum length of 15 characters.
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Enter text:
 *     <input type="email" ng-model="field" name="myField" required maxlength="15" />
 *   </label>
 *   <div ng-messages="myForm.myField.$error" role="alert">
 *     <div ng-message="required">Please enter a value for this field.</div>
 *     <div ng-message="email">This field must be a valid email address.</div>
 *     <div ng-message="maxlength">This field can be at most 15 characters long.</div>
 *   </div>
 * </form>
 * ```
 *
 * In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute
 * set to the `$error` object owned by the `myField` input in our `myForm` form.
 *
 * Within this element we then create separate elements for each of the possible errors that `myField` could have.
 * The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,
 * setting `ng-message="required"` specifies that this particular element should be displayed when there
 * is no value present for the required field `myField` (because the key `required` will be `true` in the object
 * `myForm.myField.$error`).
 *
 * ### Message order
 *
 * By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more
 * than one message (or error) key is currently true, then which message is shown is determined by the order of messages
 * in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have
 * to prioritize messages using custom JavaScript code.
 *
 * Given the following error object for our example (which informs us that the field `myField` currently has both the
 * `required` and `email` errors):
 *
 * ```javascript
 * <!-- keep in mind that ngModel automatically sets these error flags -->
 * myField.$error = { required : true, email: true, maxlength: false };
 * ```
 * The `required` message will be displayed to the user since it appears before the `email` message in the DOM.
 * Once the user types a single character, the `required` message will disappear (since the field now has a value)
 * but the `email` message will be visible because it is still applicable.
 *
 * ### Displaying multiple messages at the same time
 *
 * While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can
 * be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:
 *
 * ```html
 * <!-- attribute-style usage -->
 * <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
 *
 * <!-- element-style usage -->
 * <ng-messages for="myForm.myField.$error" multiple>...</ng-messages>
 * ```
 *
 * ## Reusing and Overriding Messages
 * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
 * template. This allows for generic collection of messages to be reused across multiple parts of an
 * application.
 *
 * ```html
 * <script type="text/ng-template" id="error-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <div ng-messages="myForm.myField.$error" role="alert">
 *   <div ng-messages-include="error-messages"></div>
 * </div>
 * ```
 *
 * However, including generic messages may not be useful enough to match all input fields, therefore,
 * `ngMessages` provides the ability to override messages defined in the remote template by redefining
 * them within the directive container.
 *
 * ```html
 * <!-- a generic template of error messages known as "my-custom-messages" -->
 * <script type="text/ng-template" id="my-custom-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            id="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <!-- any ng-message elements that appear BEFORE the ng-messages-include will
 *        override the messages present in the ng-messages-include template -->
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <!-- this required message has overridden the template message -->
 *     <div ng-message="required">You did not enter your email address</div>
 *
 *     <!-- this is a brand new message and will appear last in the prioritization -->
 *     <div ng-message="email">Your email address is invalid</div>
 *
 *     <!-- and here are the generic error messages -->
 *     <div ng-messages-include="my-custom-messages"></div>
 *   </div>
 * </form>
 * ```
 *
 * In the example HTML code above the message that is set on required will override the corresponding
 * required message defined within the remote template. Therefore, with particular input fields (such
 * email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied
 * while more generic messages can be used to handle other, more general input errors.
 *
 * ## Dynamic Messaging
 * ngMessages also supports using expressions to dynamically change key values. Using arrays and
 * repeaters to list messages is also supported. This means that the code below will be able to
 * fully adapt itself and display the appropriate message when any of the expression data changes:
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message="required">You did not enter your email address</div>
 *     <div ng-repeat="errorMessage in errorMessages">
 *       <!-- use ng-message-exp for a message whose key is given by an expression -->
 *       <div ng-message-exp="errorMessage.type">{{ errorMessage.text }}</div>
 *     </div>
 *   </div>
 * </form>
 * ```
 *
 * The `errorMessage.type` expression can be a string value or it can be an array so
 * that multiple errors can be associated with a single error message:
 *
 * ```html
 *   <label>
 *     Email address
 *     <input type="email"
 *            ng-model="data.email"
 *            name="myEmail"
 *            ng-minlength="5"
 *            ng-maxlength="100"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message-exp="'required'">You did not enter your email address</div>
 *     <div ng-message-exp="['minlength', 'maxlength']">
 *       Your email must be between 5 and 100 characters long
 *     </div>
 *   </div>
 * ```
 *
 * Feel free to use other structural directives such as ng-if and ng-switch to further control
 * what messages are active and when. Be careful, if you place ng-message on the same element
 * as these structural directives, Angular may not be able to determine if a message is active
 * or not. Therefore it is best to place the ng-message on a child element of the structural
 * directive.
 *
 * ```html
 * <div ng-messages="myForm.myEmail.$error" role="alert">
 *   <div ng-if="showRequiredError">
 *     <div ng-message="required">Please enter something</div>
 *   </div>
 * </div>
 * ```
 *
 * ## Animations
 * If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and
 * `ngMessageExp` directives will trigger animations whenever any messages are added and removed from
 * the DOM by the `ngMessages` directive.
 *
 * Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS
 * class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no
 * messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can
 * hook into the animations whenever these classes are added/removed.
 *
 * Let's say that our HTML code for our messages container looks like so:
 *
 * ```html
 * <div ng-messages="myMessages" class="my-messages" role="alert">
 *   <div ng-message="alert" class="some-message">...</div>
 *   <div ng-message="fail" class="some-message">...</div>
 * </div>
 * ```
 *
 * Then the CSS animation code for the message container looks like so:
 *
 * ```css
 * .my-messages {
 *   transition:1s linear all;
 * }
 * .my-messages.ng-active {
 *   // messages are visible
 * }
 * .my-messages.ng-inactive {
 *   // messages are hidden
 * }
 * ```
 *
 * Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter
 * and leave animation is triggered for each particular element bound to the `ngMessage` directive.
 *
 * Therefore, the CSS code for the inner messages looks like so:
 *
 * ```css
 * .some-message {
 *   transition:1s linear all;
 * }
 *
 * .some-message.ng-enter {}
 * .some-message.ng-enter.ng-enter-active {}
 *
 * .some-message.ng-leave {}
 * .some-message.ng-leave.ng-leave-active {}
 * ```

   * `ngMessages` manages the state of internal messages within its container element. The internal
   * messages use the `ngMessage` directive and will be inserted/removed from the page depending
   * on if they're present within the key/value object. By default, only one message will be displayed
   * at a time and this depends on the prioritization of the messages within the template. (This can
   * be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)
   *
   * A remote template can also be used to promote message reusability and messages can also be
   * overridden.

   *  - **maxBatchedRequestPerCall** – `{int}` – The maximum number of single http request that are allow to be
   *      sent in one http batch request.
   *  - **minimumBatchSize** - `{int}` - Defaults to 1.  The smallest number of individual calls allowed in a batch request.
   * - **batchRequestCollectionDelay** - `{int}` - The default time in milliseconds the http batcher should wait to collection all request to this domain after
   *      the first http call that can be batched has been collect.  This defaults to 100ms.  Therefore if you send
   *      a HTTP GET call that can be batched the HTTP batcher will receive this call and wait a further 100ms before
   *      sending the call in order to wait for other calls to the same domain in order to add them to the current batch
   *      request.  If no other calls are collected the initial HTTP call will be allowed to continue as normal and will
   *      not be batched unless the config property - **minimumBatchSize** is set to one.
   *  - **ignoredVerbs** - The HTTP verbs that are ignored and not included in a batch request.  By default only HEAD request are ignored.
   *  - **sendCookies** - True indicates that cookies will be send within each request segment in the batch request.  Note
   *      only non HTTPOnly cookies can be sent as Javascript cannot access HTTPOnly cookies for security reasons.  This
   *      property is false by default to reduce request size.
   *  - **enabled** True indicates batching is enabled.  The default is true.  If the property is false the batcher will
   *      send request down the normal $http pipeline and request will not be batched.
   *  - **canBatchRequest** - An optional function which determines if the request can be batched.  It takes in the url
   *      and http method of a pending request and returns true if this request can be batched otherwise false.
   *  - **batchRequestHeaders** - An optional object of header keys and values that will be added to a batched request header's before

             * Our basic approach here for event handlers is that we listen for a down event (mousedown or touchstart).
             * Once we have a down event, we need to work out whether we have a click, a drag, or a
             * hold.  A click would sort the grid (if sortable).  A drag would be used by moveable, so
             * we ignore it.  A hold would open the menu.
             *
             * So, on down event, we put in place handlers for move and up events, and a timer.  If the
             * timer expires before we see a move or up, then we have a long press and hence a column menu open.
             * If the up happens before the timer, then we have a click, and we sort if the column is sortable.
             * If a move happens before the timer, then we are doing column move, so we do nothing, the moveable feature
             * will handle it.
             *
             * To deal with touch enabled devices that also have mice, we only create our handlers when
             * we get the down event, and we create the corresponding handlers - if we're touchstart then
             * we get touchmove and touchend, if we're mousedown then we get mousemove and mouseup.
             *
             * We also suppress the click action whilst this is happening - otherwise after the mouseup there
             * will be a click event and that can cause the column menu to close
             *

   * @description creates or removes GridRow objects from the newRawData array.  Calls each registered
   * rowBuilder to further process the row
   * @param {array} newRawData Modified set of data
   *
   * This method aims to achieve three things:
   * 1. the resulting rows array is in the same order as the newRawData, we'll call
   * rowsProcessors immediately after to sort the data anyway
   * 2. if we have row hashing available, we try to use the rowHash to find the row
   * 3. no memory leaks - rows that are no longer in newRawData need to be garbage collected
   *
   * The basic logic flow makes use of the newRawData, oldRows and oldHash, and creates
   * the newRows and newHash
   *
   * ```
   * newRawData.forEach newEntity
   *   if (hashing enabled)
   *     check oldHash for newEntity
   *   else
   *     look for old row directly in oldRows
   *   if !oldRowFound     // must be a new row
   *     create newRow
   *   append to the newRows and add to newHash
   *   run the processors
   * ```
   *
   * Rows are identified using the hashKey if configured.  If not configured, then rows
   * are identified using the gridOptions.rowEquality function
   *
   * This method is useful when trying to select rows immediately after loading data without
   * using a $timeout/$interval, e.g.:
   *
   *   $scope.gridOptions.data =  someData;
   *   $scope.gridApi.grid.modifyRows($scope.gridOptions.data);
   *   $scope.gridApi.selection.selectRow($scope.gridOptions.data[0]);

   * originally selected rows to be re-selected))

       * @description (mandatory) Array of data to be rendered into the grid, providing the data source or data binding for
       * the grid.
       *
       * Most commonly the data is an array of objects, where each object has a number of attributes.
       * Each attribute automatically becomes a column in your grid.  This array could, for example, be sourced from
       * an angularJS $resource query request.  The array can also contain complex objects, refer the binding tutorial
       * for examples of that.
       *
       * The most flexible usage is to set your data on $scope:
       *
       * `$scope.data = data;`
       *
       * And then direct the grid to resolve whatever is in $scope.data:
       *
       * `$scope.gridOptions.data = 'data';`
       *
       * This is the most flexible approach as it allows you to replace $scope.data whenever you feel like it without
       * getting pointer issues.
       *
       * Alternatively you can directly set the data array:
       *
       * `$scope.gridOptions.data = [ ];`
       * or
       *
       * `$http.get('/data/100.json')

       *   $scope.myData = data;
       *   $scope.gridOptions.data = $scope.myData;
       *  });`
       *
       * Where you do this, you need to take care in updating the data - you can't just update `$scope.myData` to some other
       * array, you need to update $scope.gridOptions.data to point to that new array as well.

     *  @name updateColumnWidths
     *  @propertyOf  ui.grid.class:GridRenderContainer
     *  @description Determine the appropriate column width of each column across all render containers.
     *
     *  Column width is easy when each column has a specified width.  When columns are variable width (i.e.
     *  have an * or % of the viewport) then we try to calculate so that things fit in.  The problem is that
     *  we have multiple render containers, and we don't want one render container to just take the whole viewport
     *  when it doesn't need to - we want things to balance out across the render containers.
     *
     *  To do this, we use this method to calculate all the renderContainers, recognising that in a given render
     *  cycle it'll get called once per render container, so it needs to return the same values each time.
     *
     *  The constraints on this method are therefore:
     *  - must return the same value when called multiple times, to do this it needs to rely on properties of the
     *    columns, but not properties that change when this is called (so it shouldn't rely on drawnWidth)
     *
     *  The general logic of this method is:
     *  - calculate our total available width
     *  - look at all the columns across all render containers, and work out which have widths and which have
     *    constraints such as % or * or something else
     *  - for those with *, count the total number of * we see and add it onto a running total, add this column to an * array
     *  - for those with a %, allocate the % as a percentage of the viewport, having consideration of min and max
     *  - for those with manual width (in pixels) we set the drawnWidth to the specified width
     *  - we end up with an asterisks array still to process
     *  - we look at our remaining width.  If it's greater than zero, we divide it up among the asterisk columns, then process
     *    them for min and max width constraints
     *  - if it's zero or less, we set the asterisk columns to their minimum widths
     *  - we use parseInt quite a bit, as we try to make all our column widths integers

   *
   * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
   *
   * This module provides grouping of rows based on the data in them, similar
   * in concept to excel grouping.  You can group multiple columns, resulting in
   * nested grouping.
   *
   * In concept this feature is similar to sorting + grid footer/aggregation, it
   * sorts the data based on the grouped columns, then creates group rows that
   * reflect a break in the data.  Each of those group rows can have aggregations for
   * the data within that group.
   *
   * This feature leverages treeBase to provide the tree functionality itself,
   * the key thing this feature does therefore is to set treeLevels on the rows
   * and insert the group headers.
   *
   * Design information:
   * -------------------
   *
   * Each column will get new menu items - group by, and aggregate by.  Group by
   * will cause this column to be sorted (if not already), and will move this column
   * to the front of the sorted columns (i.e. grouped columns take precedence over
   * sorted columns).  It will respect the sort order already set if there is one,
   * and it will allow the sorting logic to change that sort order, it just forces
   * the column to the front of the sorting.  You can group by multiple columns, the
   * logic will add this column to the sorting after any already grouped columns.
   *
   * Once a grouping is defined, grouping logic is added to the rowsProcessors.  This
   * will process the rows, identifying a break in the data value, and inserting a grouping row.
   * Grouping rows have specific attributes on them:
   *
   *  - internalRow = true: tells us that this isn't a real row, so we can ignore it
   *    from any processing that it looking at core data rows.  This is used by the core
   *    logic (or will be one day), as it's not grouping specific
   *  - groupHeader = true: tells us this is a groupHeader.  This is used by the grouping logic
   *    to know if this is a groupHeader row or not
   *
   * Since the logic is baked into the rowsProcessors, it should get triggered whenever
   * row order or filtering or anything like that is changed.  In order to avoid the row instantiation
   * time, and to preserve state across invocations, we hold a cache of the rows that we created
   * last time, and we use them again this time if we can.
   *
   * By default rows are collapsed, which means all data rows have their visible property
   * set to false, and only level 0 group rows are set to visible.

   *
   * This module provides the ability to import data into the grid. It
   * uses the column defs to work out which data belongs in which column,
   * and creates entities from a configured class (typically a $resource).
   *
   * If the rowEdit feature is enabled, it also calls save on those newly
   * created objects, and then displays any errors in the imported data.
   *
   * Currently the importer imports only CSV and json files, although provision has been
   * made to process other file formats, and these can be added over time.
   *
   * For json files, the properties within each object in the json must match the column names
   * (to put it another way, the importer doesn't process the json, it just copies the objects
   * within the json into a new instance of the specified object type)
   *
   * For CSV import, the default column identification relies on each column in the
   * header row matching a column.name or column.displayName. Optionally, a column identification
   * callback can be used.  This allows matching using other attributes, which is particularly
   * useful if your application has internationalised column headings (i.e. the headings that
   * the user sees don't match the column names).
   *
   * The importer makes use of the grid menu as the UI for requesting an
   * import.

  /**
   * @ngdoc overview
   * @name ui.grid.treeBase
   * @description
   *
   * # ui.grid.treeBase
   *
   * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
   *
   * This module provides base tree handling functions that are shared by other features, notably grouping
   * and treeView.  It provides a tree view of the data, with nodes in that
   * tree and leaves.
   *
   * Design information:
   * -------------------
   *
   * The raw data that is provided must come with a $$treeLevel on any non-leaf node.  Grouping will create
   * these on all the group header rows, treeView will expect these to be set in the raw data by the user.
   * TreeBase will run a rowsProcessor that:
   *  - builds `treeBase.tree` out of the provided rows
   *  - permits a recursive sort of the tree
   *  - maintains the expand/collapse state of each node
   *  - provides the expand/collapse all button and the expand/collapse buttons
   *  - maintains the count of children for each node
   *
   * Each row is updated with a link to the tree node that represents it.  Refer {@link ui.grid.treeBase.grid:treeBase.tree tree documentation}
   * for information.
   *
   *  TreeBase adds information to the rows
   *  - treeLevel: if present and > -1 tells us the level (level 0 is the top level)
   *  - treeNode: pointer to the node in the grid.treeBase.tree that refers
   *    to this row, allowing us to manipulate the state
   *
   * Since the logic is baked into the rowsProcessors, it should get triggered whenever
   * row order or filtering or anything like that is changed.  We recall the expanded state
   * across invocations of the rowsProcessors by the reference to the treeNode on the individual
   * rows.  We rebuild the tree itself quite frequently, when we do this we use the saved treeNodes to
   * get the state, but we overwrite the other data in that treeNode.
   *
   * By default rows are collapsed, which means all data rows have their visible property
   * set to false, and only level 0 group rows are set to visible.
   *
   * We rely on the rowsProcessors to do the actual expanding and collapsing, so we set the flags we want into
   * grid.treeBase.tree, then call refresh.  This is because we can't easily change the visible
   * row cache without calling the processors, and once we've built the logic into the rowProcessors we may as
   * well use it all the time.
   *
   * Tree base provides sorting (on non-grouped columns).
   *
   * Sorting works in two passes.  The standard sorting is performed for any columns that are important to building
   * the tree (for example, any grouped columns).  Then after the tree is built, a recursive tree sort is performed
   * for the remaining sort columns (including the original sort) - these columns are sorted within each tree level
   * (so all the level 1 nodes are sorted, then all the level 2 nodes within each level 1 node etc).
   *
   * To achieve this we make use of the `ignoreSort` property on the sort configuration.  The parent feature (treeView or grouping)
   * must provide a rowsProcessor that runs with very low priority (typically in the 60-65 range), and that sets
   * the `ignoreSort`on any sort that it wants to run on the tree.  TreeBase will clear the ignoreSort on all sorts - so it
   * will turn on any sorts that haven't run.  It will then call a recursive sort on the tree.
   *
   * Tree base provides treeAggregation.  It checks the treeAggregation configuration on each column, and aggregates based on
   * the logic provided as it builds the tree. Footer aggregation from the uiGrid core should not be used with treeBase aggregation,
   * since it operates on all visible rows, as opposed to to leaf nodes only. Setting `showColumnFooter: true` will show the
   * treeAggregations in the column footer.  Aggregation information will be collected in the format:
   *
   * ```
   *   {
   *     type: 'count',
   *     value: 4,
   *     label: 'count: ',
   *     rendered: 'count: 4'
   *   }
   * ```
   *
   * A callback is provided to format the value once it is finalised (aka a valueFilter).
   *

 *   Sanitizes an html string by stripping all potentially dangerous tokens.
 *
 *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
 *   then serialized back to properly escaped html string. This means that no unsafe input can make
 *   it into the returned string.
 *
 *   The whitelist for URL sanitization of attribute values is configured using the functions
 *   `aHrefSanitizationWhitelist` and `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider
 *   `$compileProvider`}.
 *
 *   The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.

 * @param {string} html HTML input.

 * @ngdoc filter
 * @name linky
 * @kind function
 *
 * @description
 * Finds links in text input and turns them into html links. Supports `http/https/ftp/mailto` and
 * plain email address links.
 *
 * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
 *
 * @param {string} text Input text.
 * @param {string} target Window (`_blank|_self|_parent|_top`) or named frame to open links in.
 * @param {object|function(url)} [attributes] Add custom attributes to the link element.
 *
 *    Can be one of:
 *
 *    - `object`: A map of attributes
 *    - `function`: Takes the url as a parameter and returns a map of attributes
 *
 *    If the map of attributes contains a value for `target`, it overrides the value of
 *    the target parameter.
 *
 *
 * @returns {string} Html-linkified and {@link $sanitize sanitized} text.

		 *
		 * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
		 *
		 * Solution:
		 *
		 * We assume the radius of the polygon is half the size of the canvas at first
		 * at each index we check if the text overlaps.
		 *
		 * Where it does, we store that angle and that index.
		 *
		 * After finding the largest index and angle we calculate how much we need to remove
		 * from the shape radius to move the point inwards by that x.
		 *
		 * We average the left and right distances to get the maximum shape radius that can fit in the box
		 * along with labels.
		 *
		 * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
		 * on each side, removing that from the size, halving it and adding the left x protrusion width.
		 *
		 * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
		 * and position it in the most space efficient manner
		 *

/* Utility class that uses d3.bisect to find the index in a given array, where a search value can be inserted.
 This is different from normal bisectLeft; this function finds the nearest index to insert the search value.

 For instance, lets say your array is [1,2,3,5,10,30], and you search for 28.
 Normal d3.bisectLeft will return 4, because 28 is inserted after the number 10.  But interactiveBisect will return 5
 because 28 is closer to 30 than 10.

 Unit tests can be found in: interactiveBisectTest.html

 Has the following known issues:
 * Will not work if the data points move backwards (ie, 10,9,8,7, etc) or if the data points are in random order.
 * Won't work if there are duplicate x coordinate values.

    // expensive (points * objects for the GC every update).
    // - ES6 function names for implicit keys would be nice but

    // - function.toString to obtain implicit keys is possible
    // but long object keys are not free (internal hash).
    // - Explicit key without objects are the most efficient.
