+ * @ngdoc module
+ * @name ngAnimate
+ * @description
+ *
+ * # ngAnimate
+ *
+ * The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives.
+ *
+ *
+ * <div doc-module-components="ngAnimate"></div>
+ *
+ * # Usage
+ *
+ * To see animations in action, all that is required is to define the appropriate CSS classes
+ * or to register a JavaScript animation via the myModule.animation() function. The directives that support animation automatically are:
+ * `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation
+ * by using the `$animate` service.
+ *
+ * Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:
+ *
+ * | Directive | Supported Animations |
+ * |---------------------------------------------------------- |----------------------------------------------------|
+ * | {@link ng.directive:ngRepeat#usage_animations ngRepeat} | enter, leave and move |
+ * | {@link ngRoute.directive:ngView#usage_animations ngView} | enter and leave |
+ * | {@link ng.directive:ngInclude#usage_animations ngInclude} | enter and leave |
+ * | {@link ng.directive:ngSwitch#usage_animations ngSwitch} | enter and leave |
+ * | {@link ng.directive:ngIf#usage_animations ngIf} | enter and leave |
+ * | {@link ng.directive:ngClass#usage_animations ngClass} | add and remove |
+ * | {@link ng.directive:ngShow#usage_animations ngShow & ngHide} | add and remove (the ng-hide class value) |
+ * | {@link ng.directive:form#usage_animations form} | add and remove (dirty, pristine, valid, invalid & all other validations) |
+ * | {@link ng.directive:ngModel#usage_animations ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) |
+ *
+ * You can find out more information about animations upon visiting each directive page.
+ *
+ * Below is an example of how to apply animations to a directive that supports animation hooks:
+ *
+ * ```html
+ * <style type="text/css">
+ * .slide.ng-enter, .slide.ng-leave {
+ * -webkit-transition:0.5s linear all;
+ * transition:0.5s linear all;
+ * }
+ *
+ * .slide.ng-enter { } /* starting animations for enter */
+ * .slide.ng-enter.ng-enter-active { } /* terminal animations for enter */
+ * .slide.ng-leave { } /* starting animations for leave */
+ * .slide.ng-leave.ng-leave-active { } /* terminal animations for leave */
+ * </style>
+ *
+ * <!--
+ * the animate service will automatically add .ng-enter and .ng-leave to the element
+ * to trigger the CSS transition/animations
+ * -->
+ * <ANY class="slide" ng-include="..."></ANY>
+ * ```
+ *
+ * Keep in mind that, by default, if an animation is running, any child elements cannot be animated
+ * until the parent element's animation has completed. This blocking feature can be overridden by
+ * placing the `ng-animate-children` attribute on a parent container tag.
+ *
+ * ```html
+ * <div class="slide-animation" ng-if="on" ng-animate-children>
+ * <div class="fade-animation" ng-if="on">
+ * <div class="explode-animation" ng-if="on">
+ * ...
+ * </div>
+ * </div>
+ * </div>
+ * ```
+ *
+ * When the `on` expression value changes and an animation is triggered then each of the elements within
+ * will all animate without the block being applied to child elements.
+ *
+ * <h2>CSS-defined Animations</h2>
+ * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
+ * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
+ * and can be used to play along with this naming structure.
+ *
+ * The following code below demonstrates how to perform animations using **CSS transitions** with Angular:
+ *
+ * ```html
+ * <style type="text/css">
+ * /*
+ * The animate class is apart of the element and the ng-enter class
+ * is attached to the element once the enter animation event is triggered
+ * */
+ * .reveal-animation.ng-enter {
+ * -webkit-transition: 1s linear all; /* Safari/Chrome */
+ * transition: 1s linear all; /* All other modern browsers and IE10+ */
+ *
+ * /* The animation preparation code */
+ * opacity: 0;
+ * }
+ *
+ * /*
+ * Keep in mind that you want to combine both CSS
+ * classes together to avoid any CSS-specificity
+ * conflicts
+ * */
+ * .reveal-animation.ng-enter.ng-enter-active {
+ * /* The animation code itself */
+ * opacity: 1;
+ * }
+ * </style>
+ *
+ * <div class="view-container">
+ * <div ng-view class="reveal-animation"></div>
+ * </div>
+ * ```
+ *
+ * The following code below demonstrates how to perform animations using **CSS animations** with Angular:
+ *
+ * ```html
+ * <style type="text/css">
+ * .reveal-animation.ng-enter {
+ * -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */
+ * animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */
+ * }
+ * @-webkit-keyframes enter_sequence {
+ * from { opacity:0; }
+ * to { opacity:1; }
+ * }
+ * @keyframes enter_sequence {
+ * from { opacity:0; }
+ * to { opacity:1; }
+ * }
+ * </style>
+ *
+ * <div class="view-container">
+ * <div ng-view class="reveal-animation"></div>
+ * </div>
+ * ```
+ *
+ * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.
+ *
+ * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add
+ * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically
+ * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
+ * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
+ * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
+ * has no CSS transition/animation classes applied to it.
+ *
+ * <h3>CSS Staggering Animations</h3>
+ * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
+ * curtain-like effect. The ngAnimate module, as of 1.2.0, supports staggering animations and the stagger effect can be
+ * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
+ * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
+ * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
+ *
+ * ```css
+ * .my-animation.ng-enter {
+ * /* standard transition code */
+ * -webkit-transition: 1s linear all;
+ * transition: 1s linear all;
+ * opacity:0;
+ * }
+ * .my-animation.ng-enter-stagger {
+ * /* this will have a 100ms delay between each successive leave animation */
+ * -webkit-transition-delay: 0.1s;
+ * transition-delay: 0.1s;
+ *
+ * /* in case the stagger doesn't work then these two values
+ * must be set to 0 to avoid an accidental CSS inheritance */
+ * -webkit-transition-duration: 0s;
+ * transition-duration: 0s;
+ * }
+ * .my-animation.ng-enter.ng-enter-active {
+ * /* standard transition styles */
+ * opacity:1;
+ * }
+ * ```
+ *
+ * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
+ * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
+ * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
+ * will also be reset if more than 10ms has passed after the last animation has been fired.
+ *
+ * The following code will issue the **ng-leave-stagger** event on the element provided:
+ *
+ * ```js
+ * var kids = parent.children();
+ *
+ * $animate.leave(kids[0]); //stagger index=0
+ * $animate.leave(kids[1]); //stagger index=1
+ * $animate.leave(kids[2]); //stagger index=2
+ * $animate.leave(kids[3]); //stagger index=3
+ * $animate.leave(kids[4]); //stagger index=4
+ *
+ * $timeout(function() {
+ * //stagger has reset itself
+ * $animate.leave(kids[5]); //stagger index=0
+ * $animate.leave(kids[6]); //stagger index=1
+ * }, 100, false);
+ * ```
+ *
+ * Stagger animations are currently only supported within CSS-defined animations.
+ *
+ * <h2>JavaScript-defined Animations</h2>
+ * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
+ * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.
+ *
+ * ```js
+ * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application.
+ * var ngModule = angular.module('YourApp', ['ngAnimate']);
+ * ngModule.animation('.my-crazy-animation', function() {
+ * return {
+ * enter: function(element, done) {
+ * //run the animation here and call done when the animation is complete
+ * return function(cancelled) {
+ * //this (optional) function will be called when the animation
+ * //completes or when the animation is cancelled (the cancelled
+ * //flag will be set to true if cancelled).
+ * };
+ * },
+ * leave: function(element, done) { },
+ * move: function(element, done) { },
+ *
+ * //animation that can be triggered before the class is added
+ * beforeAddClass: function(element, className, done) { },
+ *
+ * //animation that can be triggered after the class is added
+ * addClass: function(element, className, done) { },
+ *
+ * //animation that can be triggered before the class is removed
+ * beforeRemoveClass: function(element, className, done) { },
+ *
+ * //animation that can be triggered after the class is removed
+ * removeClass: function(element, className, done) { }
+ * };
+ * });
+ * ```
+ *
+ * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run
+ * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits
+ * the element's CSS class attribute value and then run the matching animation event function (if found).
+ * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will
+ * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported).
+ *
+ * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
+ * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
+ * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
+ * or transition code that is defined via a stylesheet).
+ *
