 /**
- * @ngdoc module
- * @name ngAnimate
- * @description
- *
- * 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
+ * @ngdoc service
+ * @name $animateCss
+ * @kind object
  *
- * To see animations in action, all that is required is to define the appropriate CSS classes
- * or to register a JavaScript animation via the `myModule.animation()` function. The directives that support animation automatically are:
- * `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation
- * by using the `$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#animations ngRepeat}                                                        | enter, leave and move                                                    |
- * | {@link ngRoute.directive:ngView#animations ngView}                                                       | enter and leave                                                          |
- * | {@link ng.directive:ngInclude#animations ngInclude}                                                      | enter and leave                                                          |
- * | {@link ng.directive:ngSwitch#animations ngSwitch}                                                        | enter and leave                                                          |
- * | {@link ng.directive:ngIf#animations ngIf}                                                                | enter and leave                                                          |
- * | {@link ng.directive:ngClass#animations ngClass}                                                          | add and remove (the CSS class(es) present)                               |
- * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide}            | add and remove (the ng-hide class value)                                 |
- * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel}    | add and remove (dirty, pristine, valid, invalid & all other validations) |
- * | {@link module:ngMessages#animations ngMessages}                                                          | add and remove (ng-active & ng-inactive)                                 |
- * | {@link module:ngMessages#animations ngMessage}                                                           | enter and leave                                                          |
- *
- * 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;
- * }
+ * @description
+ * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
+ * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
+ * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
+ * directives to create more complex animations that can be purely driven using CSS code.
  *
- * .slide.ng-enter { }        /&#42; starting animations for enter &#42;/
- * .slide.ng-enter.ng-enter-active { } /&#42; terminal animations for enter &#42;/
- * .slide.ng-leave { }        /&#42; starting animations for leave &#42;/
- * .slide.ng-leave.ng-leave-active { } /&#42; terminal animations for leave &#42;/
- * </style>
+ * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
+ * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
  *
- * <!--
- * 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>
- * ```
+ * ## Usage
+ * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
+ * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
+ * any automatic control over cancelling animations and/or preventing animations from being run on
+ * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to
+ * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
+ * the CSS animation.
  *
- * 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.
+ * The example below shows how we can create a folding animation on an element using `ng-if`:
  *
  * ```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>
+ * <!-- notice the `fold-animation` CSS class -->
+ * <div ng-if="onOff" class="fold-animation">
+ *   This element will go BOOM
  * </div>
+ * <button ng-click="onOff=true">Fold In</button>
  * ```
  *
- * 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.
- *
- * ## Are animations run when the application starts?
- * No they are not. When an application is bootstrapped Angular will disable animations from running to avoid
- * a frenzy of animations from being triggered as soon as the browser has rendered the screen. For this to work,
- * Angular will wait for two digest cycles until enabling animations. From there on, any animation-triggering
- * layout changes in the application will trigger animations as normal.
+ * Now we create the **JavaScript animation** that will trigger the CSS transition:
  *
- * In addition, upon bootstrap, if the routing system or any directives or load remote data (via $http) then Angular
- * will automatically extend the wait time to enable animations once **all** of the outbound HTTP requests
- * are complete.
- *
- * ## CSS-defined Animations
- * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
- * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
- * and can be used to play along with this naming structure.
- *
- * The following code below demonstrates how to perform animations using **CSS transitions** with Angular:
- *
- * ```html
- * <style type="text/css">
- * /&#42;
- *  The animate class is apart of the element and the ng-enter class
- *  is attached to the element once the enter animation event is triggered
- * &#42;/
- * .reveal-animation.ng-enter {
- *  -webkit-transition: 1s linear all; /&#42; Safari/Chrome &#42;/
- *  transition: 1s linear all; /&#42; All other modern browsers and IE10+ &#42;/
- *
- *  /&#42; The animation preparation code &#42;/
- *  opacity: 0;
- * }
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       var height = element[0].offsetHeight;
+ *       return $animateCss(element, {
+ *         from: { height:'0px' },
+ *         to: { height:height + 'px' },
+ *         duration: 1 // one second
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
  *
- * /&#42;
- *  Keep in mind that you want to combine both CSS
- *  classes together to avoid any CSS-specificity
- *  conflicts
- * &#42;/
- * .reveal-animation.ng-enter.ng-enter-active {
- *  /&#42; The animation code itself &#42;/
- *  opacity: 1;
- * }
- * </style>
+ * ## More Advanced Uses
  *
- * <div class="view-container">
- *   <div ng-view class="reveal-animation"></div>
- * </div>
- * ```
+ * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
+ * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
  *
- * The following code below demonstrates how to perform animations using **CSS animations** with Angular:
+ * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
+ * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
+ * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
+ * to provide a working animation that will run in CSS.
  *
- * ```html
- * <style type="text/css">
- * .reveal-animation.ng-enter {
- *   -webkit-animation: enter_sequence 1s linear; /&#42; Safari/Chrome &#42;/
- *   animation: enter_sequence 1s linear; /&#42; IE10+ and Future Browsers &#42;/
- * }
- * @-webkit-keyframes enter_sequence {
- *   from { opacity:0; }
- *   to { opacity:1; }
- * }
- * @keyframes enter_sequence {
- *   from { opacity:0; }
- *   to { opacity:1; }
- * }
- * </style>
+ * The example below showcases a more advanced version of the `.fold-animation` from the example above:
  *
- * <div class="view-container">
- *   <div ng-view class="reveal-animation"></div>
- * </div>
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       var height = element[0].offsetHeight;
+ *       return $animateCss(element, {
+ *         addClass: 'red large-text pulse-twice',
+ *         easing: 'ease-out',
+ *         from: { height:'0px' },
+ *         to: { height:height + 'px' },
+ *         duration: 1 // one second
+ *       });
+ *     }
+ *   }
+ * }]);
  * ```
  *
- * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.
- *
- * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add
- * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically
- * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
- * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
- * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
- * has no CSS transition/animation classes applied to it.
- *
- * ### Structural transition animations
- *
- * Structural transitions (such as enter, leave and move) will always apply a `0s none` transition
- * value to force the browser into rendering the styles defined in the setup (`.ng-enter`, `.ng-leave`
- * or `.ng-move`) class. This means that any active transition animations operating on the element
- * will be cut off to make way for the enter, leave or move animation.
- *
- * ### Class-based transition animations
- *
- * Class-based transitions refer to transition animations that are triggered when a CSS class is
- * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`,
- * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`).
- * They are different when compared to structural animations since they **do not cancel existing
- * animations** nor do they **block successive transitions** from rendering on the same element.
- * This distinction allows for **multiple class-based transitions** to be performed on the same element.
- *
- * In addition to ngAnimate supporting the default (natural) functionality of class-based transition
- * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the
- * developer in further styling the element throughout the transition animation. Earlier versions
- * of ngAnimate may have caused natural CSS transitions to break and not render properly due to
- * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class
- * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of
- * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS
- * class transitions are compatible with ngAnimate.
- *
- * There is, however, one special case when dealing with class-based transitions in ngAnimate.
- * When rendering class-based transitions that make use of the setup and active CSS classes
- * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define
- * the transition value **on the active CSS class** and not the setup class.
+ * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
  *
  * ```css
- * .fade-add {
- *   /&#42; remember to place a 0s transition here
- *      to ensure that the styles are applied instantly
- *      even if the element already has a transition style &#42;/
- *   transition:0s linear all;
- *
- *   /&#42; starting CSS styles &#42;/
- *   opacity:1;
+ * /&#42; since a hardcoded duration value of 1 was provided in the JavaScript animation code,
+ * the CSS classes below will be transitioned despite them being defined as regular CSS classes &#42;/
+ * .red { background:red; }
+ * .large-text { font-size:20px; }
+ *
+ * /&#42; we can also use a keyframe animation and $animateCss will make it work alongside the transition &#42;/
+ * .pulse-twice {
+ *   animation: 0.5s pulse linear 2;
+ *   -webkit-animation: 0.5s pulse linear 2;
  * }
- * .fade-add.fade-add-active {
- *   /&#42; this will be the length of the animation &#42;/
- *   transition:1s linear all;
- *   opacity:0;
- * }
- * ```
  *
- * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it
- * has a duration of zero. This may not be required, however, incase the browser is unable to render
- * the styling present in this CSS class instantly then it could be that the browser is attempting
- * to perform an unnecessary transition.
- *
- * This workaround, however, does not apply to  standard class-based transitions that are rendered
- * when a CSS class containing a transition is applied to an element:
+ * @keyframes pulse {
+ *   from { transform: scale(0.5); }
+ *   to { transform: scale(1.5); }
+ * }
  *
- * ```css
- * /&#42; this works as expected &#42;/
- * .fade {
- *   transition:1s linear all;
- *   opacity:0;
+ * @-webkit-keyframes pulse {
+ *   from { -webkit-transform: scale(0.5); }
+ *   to { -webkit-transform: scale(1.5); }
  * }
  * ```
  *
- * Please keep this in mind when coding the CSS markup that will be used within class-based transitions.
- * Also, try not to mix the two class-based animation flavors together since the CSS code may become
- * overly complex.
- *
- *
- * ### Preventing Collisions With Third Party Libraries
- *
- * Some third-party frameworks place animation duration defaults across many element or className
- * selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which
- * is expecting actual animations on these elements and has to wait for their completion.
- *
- * You can prevent this unwanted behavior by using a prefix on all your animation classes:
+ * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
  *
- * ```css
- * /&#42; prefixed with animate- &#42;/
- * .animate-fade-add.animate-fade-add-active {
- *   transition:1s linear all;
- *   opacity:0;
- * }
- * ```
+ * ## How the Options are handled
  *
- * You then configure `$animate` to enforce this prefix:
+ * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
+ * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
+ * styles using the `from` and `to` properties.
  *
  * ```js
- * $animateProvider.classNameFilter(/animate-/);
+ * var animator = $animateCss(element, {
+ *   from: { background:'red' },
+ *   to: { background:'blue' }
+ * });
+ * animator.start();
  * ```
- * </div>
- *
- * ### CSS Staggering Animations
- * 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 (versions >=1.2) 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 {
- *   /&#42; standard transition code &#42;/
- *   -webkit-transition: 1s linear all;
- *   transition: 1s linear all;
- *   opacity:0;
+ * .rotating-animation {
+ *   animation:0.5s rotate linear;
+ *   -webkit-animation:0.5s rotate linear;
  * }
- * .my-animation.ng-enter-stagger {
- *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
- *   -webkit-transition-delay: 0.1s;
- *   transition-delay: 0.1s;
  *
- *   /&#42; in case the stagger doesn't work then these two values
- *    must be set to 0 to avoid an accidental CSS inheritance &#42;/
- *   -webkit-transition-duration: 0s;
- *   transition-duration: 0s;
+ * @keyframes rotate {
+ *   from { transform: rotate(0deg); }
+ *   to { transform: rotate(360deg); }
  * }
- * .my-animation.ng-enter.ng-enter-active {
- *   /&#42; standard transition styles &#42;/
- *   opacity:1;
+ *
+ * @-webkit-keyframes rotate {
+ *   from { -webkit-transform: rotate(0deg); }
+ *   to { -webkit-transform: rotate(360deg); }
  * }
  * ```
  *
- * 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
- *   $animate.leave(kids[6]); //stagger index=1
- * }, 100, false);
- * ```
+ * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
+ * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
+ * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
+ * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
+ * and spread across the transition and keyframe animation.
  *
- * Stagger animations are currently only supported within CSS-defined animations.
+ * ## What is returned
  *
- * ## JavaScript-defined Animations
- * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
- * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.
+ * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
+ * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
+ * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
  *
  * ```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) { }
- *   };
- * });
+ * var animator = $animateCss(element, { ... });
  * ```
  *
- * 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, $animate will look for a matching animation which fits
- * the element's CSS class attribute value and then run the matching animation event function (if found).
- * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will
- * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported).
- *
- * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
- * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
- * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
- * or transition code that is defined via a stylesheet).
- *
- *
- * ### Applying Directive-specific Styles to an Animation
- * In some cases a directive or service may want to provide `$animate` with extra details that the animation will
- * include into its animation. Let's say for example we wanted to render an animation that animates an element
- * towards the mouse coordinates as to where the user clicked last. By collecting the X/Y coordinates of the click
- * (via the event parameter) we can set the `top` and `left` styles into an object and pass that into our function
- * call to `$animate.addClass`.
+ * Now what do the contents of our `animator` variable look like:
  *
  * ```js
- * canvas.on('click', function(e) {
- *   $animate.addClass(element, 'on', {
- *     to: {
- *       left : e.client.x + 'px',
- *       top : e.client.y + 'px'
- *     }
- *   }):
- * });
- * ```
+ * {
+ *   // starts the animation
+ *   start: Function,
  *
- * Now when the animation runs, and a transition or keyframe animation is picked up, then the animation itself will
- * also include and transition the styling of the `left` and `top` properties into its running animation. If we want
- * to provide some starting animation values then we can do so by placing the starting animations styles into an object
- * called `from` in the same object as the `to` animations.
- *
- * ```js
- * canvas.on('click', function(e) {
- *   $animate.addClass(element, 'on', {
- *     from: {
- *        position: 'absolute',
- *        left: '0px',
- *        top: '0px'
- *     },
- *     to: {
- *       left : e.client.x + 'px',
- *       top : e.client.y + 'px'
- *     }
- *   }):
- * });
+ *   // ends (aborts) the animation
+ *   end: Function
+ * }
  * ```
  *
- * Once the animation is complete or cancelled then the union of both the before and after styles are applied to the
- * element. If `ngAnimate` is not present then the styles will be applied immediately.
- *
+ * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
+ * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and stlyes may have been
+ * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
+ * and that changing them will not reconfigure the parameters of the animation.
+ *
+ * ### runner.done() vs runner.then()
+ * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
+ * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
+ * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
+ * unless you really need a digest to kick off afterwards.
+ *
+ * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
+ * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
+ * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
+ *
+ * @param {DOMElement} element the element that will be animated
+ * @param {object} options the animation-related options that will be applied during the animation
+ *
+ * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
+ * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
+ * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
+ * * `transition` - The raw CSS transition style that will be used (e.g. `1s linear all`).
+ * * `keyframe` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
+ * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
+ * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
+ * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
+ * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
+ * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
+ * is provided then the animation will be skipped entirely.
+ * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
+ * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
+ * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
+ * CSS delay value.
+ * * `stagger` - A numeric time value representing the delay between successively animated elements
+ * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
+ * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
+ * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
+ * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occuring on the classes being added and removed.)
+ *
+ * @return {object} an object with start and end methods and details about the animation.
+ *
+ * * `start` - The method to start the animation. This will return a `Promise` when called.
+ * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

-      /**
-       * @ngdoc service
-       * @name $animate
-       * @kind object
-       *
-       * @description
-       * The `$animate` service provides animation detection support while performing DOM operations (enter, leave and move) as well as during addClass and removeClass operations.
-       * When any of these operations are run, the $animate service
-       * will examine any JavaScript-defined animations (which are defined by using the $animateProvider provider object)
-       * as well as any CSS-defined animations against the CSS classes present on the element once the DOM operation is run.
-       *
-       * The `$animate` service is used behind the scenes with pre-existing directives and animation with these directives
-       * will work out of the box without any extra configuration.
-       *
-       * Requires the {@link ngAnimate `ngAnimate`} module to be installed.
-       *
-       * Please visit the {@link ngAnimate `ngAnimate`} module overview page learn more about how to use animations in your application.
-       * ## Callback Promises
-       * With AngularJS 1.3, each of the animation methods, on the `$animate` service, return a promise when called. The
-       * promise itself is then resolved once the animation has completed itself, has been cancelled or has been
-       * skipped due to animations being disabled. (Note that even if the animation is cancelled it will still
-       * call the resolve function of the animation.)
-       *
-       * ```js
-       * $animate.enter(element, container).then(function() {
-       *   //...this is called once the animation is complete...
-       * });
-       * ```
-       *
-       * Also note that, due to the nature of the callback promise, if any Angular-specific code (like changing the scope,
-       * location of the page, etc...) is executed within the callback promise then be sure to wrap the code using
-       * `$scope.$apply(...)`;
-       *
-       * ```js
-       * $animate.leave(element).then(function() {
-       *   $scope.$apply(function() {
-       *     $location.path('/new-page');
-       *   });
-       * });
-       * ```
-       *
-       * An animation can also be cancelled by calling the `$animate.cancel(promise)` method with the provided
-       * promise that was returned when the animation was started.
-       *
-       * ```js
-       * var promise = $animate.addClass(element, 'super-long-animation');
-       * promise.then(function() {
-       *   //this will still be called even if cancelled
-       * });
-       *
-       * element.on('click', function() {
-       *   //tooo lazy to wait for the animation to end
-       *   $animate.cancel(promise);
-       * });
-       * ```
-       *
-       * (Keep in mind that the promise cancellation is unique to `$animate` since promises in
-       * general cannot be cancelled.)
-       *

-         * |-----------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------|
-         * | 1. `$animate.animate(...)` is called                                                                                  | `class="my-animation"`                                       |
-         * | 2. `$animate` waits for the next digest to start the animation                                                        | `class="my-animation ng-animate"`                            |
-         * | 3. `$animate` runs the JavaScript-defined animations detected on the element                                          | `class="my-animation ng-animate"`                            |
-         * | 4. the `className` class value is added to the element                                                                | `class="my-animation ng-animate className"`                  |
-         * | 5. `$animate` scans the element styles to get the CSS transition/animation duration and delay                         | `class="my-animation ng-animate className"`                  |
-         * | 6. `$animate` blocks all CSS transitions on the element to ensure the `.className` class styling is applied right away| `class="my-animation ng-animate className"`                  |
-         * | 7. `$animate` applies the provided collection of `from` CSS styles to the element                                     | `class="my-animation ng-animate className"`                  |

-         * | 11. `$animate` applies the collection of `to` CSS styles to the element which are then handled by the transition      | `class="my-animation ng-animate className className-active"` |
-         * | 12. `$animate` waits for the animation to complete (via events and timeout)                                           | `class="my-animation ng-animate className className-active"` |
