+/**
+ * @ngdoc service
+ * @name $animateCss
+ * @kind object
+ *
+ * @description
+ * The `$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.
+ *
+ * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
+ * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
+ *
+ * ## Usage
+ * Once again, `$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 `$animateCss` to trigger
+ * the CSS animation.
+ *
+ * The example below shows how we can create a folding animation on an element using `ng-if`:
+ *
+ * ```html
+ * <!-- notice the `fold-animation` CSS class -->
+ * <div ng-if="onOff" class="fold-animation">
+ *   This element will go BOOM
+ * </div>
+ * <button ng-click="onOff=true">Fold In</button>
+ * ```
+ *
+ * Now we create the **JavaScript animation** that will trigger the CSS transition:
+ *
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       var height = element[0].offsetHeight;
+ *       return $animateCss(element, {
+ *         from: { height:'0px' },
+ *         to: { height:height + 'px' },
+ *         duration: 1 // one second
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * ## More Advanced Uses
+ *
+ * `$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 `$animateCss` via JavaScript code.
+ *
+ * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
+ * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
+ * `$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.
+ *
+ * The example below showcases a more advanced version of the `.fold-animation` from the example above:
+ *
+ * ```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
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
+ *
+ * ```css
+ * /&#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 $animateCss will make it work alongside the transition &#42;/
+ * .pulse-twice {
+ *   animation: 0.5s pulse linear 2;
+ *   -webkit-animation: 0.5s pulse linear 2;
+ * }
+ *
+ * @keyframes pulse {
+ *   from { transform: scale(0.5); }
+ *   to { transform: scale(1.5); }
+ * }
+ *
+ * @-webkit-keyframes pulse {
+ *   from { -webkit-transform: scale(0.5); }
+ *   to { -webkit-transform: scale(1.5); }
+ * }
+ * ```
+ *
+ * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
+ *
+ * ## How the Options are handled
+ *
+ * `$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
+ * var animator = $animateCss(element, {
+ *   from: { background:'red' },
+ *   to: { background:'blue' }
+ * });
+ * animator.start();
+ * ```
+ *
+ * ```css
+ * .rotating-animation {
+ *   animation:0.5s rotate linear;
+ *   -webkit-animation:0.5s rotate linear;
+ * }
+ *
+ * @keyframes rotate {
+ *   from { transform: rotate(0deg); }
+ *   to { transform: rotate(360deg); }
+ * }
+ *
+ * @-webkit-keyframes rotate {
+ *   from { -webkit-transform: rotate(0deg); }
+ *   to { -webkit-transform: rotate(360deg); }
+ * }
+ * ```
+ *
+ * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$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, `$animateCss` will automatically create an inline transition
+ * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
+ * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
+ * and spread across the transition and keyframe animation.
+ *
+ * ## What is returned
+ *
+ * `$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
+ * var animator = $animateCss(element, { ... });
+ * ```
+ *
+ * Now what do the contents of our `animator` variable look like:
+ *
+ * ```js
+ * {
+ *   // starts the animation
+ *   start: Function,
+ *
+ *   // ends (aborts) the animation
+ *   end: Function
+ * }
+ * ```
+ *
+ * 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 styles 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.)
+ * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
+ * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
+ * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
+ * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
+ * * `keyframeStyle` - 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 occurring on the classes being added and removed.)
+ * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
+ *    the animation is closed. This is useful for when the styles are used purely for the sake of
+ *    the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
+ *    By default this value is set to `false`.
+ *
+ * @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 module
+ * @name ngAnimate
+ * @description
+ *
+ * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
+ * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app.
+ *
+ * <div doc-module-components="ngAnimate"></div>
+ *
+ * # Usage
+ * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
+ * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
+ * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
+ * the HTML element that the animation will be triggered on.
+ *
+ * ## Directive Support
+ * The following directives are "animation aware":
+ *
+ * | Directive                                                                                                | Supported Animations                                                     |

+ * | {@link ngRoute.directive:ngView#animations ngView}                                                       | enter and leave                                                          |
+ * | {@link ng.directive:ngInclude#animations ngInclude}                                                      | 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                                                          |
+ *
+ * (More information can be found by visiting each the documentation associated with each directive.)
+ *
+ * ## CSS-based Animations
+ *
+ * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
+ * and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation.
+ *
+ * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
+ *
+ * ```html
+ * <div ng-if="bool" class="fade">
+ *    Fade me in out
+ * </div>
+ * <button ng-click="bool=true">Fade In!</button>
+ * <button ng-click="bool=false">Fade Out!</button>
+ * ```
+ *
+ * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
+ *
+ * ```css
+ * /&#42; The starting CSS styles for the enter animation &#42;/
+ * .fade.ng-enter {
+ *   transition:0.5s linear all;
+ *   opacity:0;
+ * }
+ *
+ * /&#42; The finishing CSS styles for the enter animation &#42;/
+ * .fade.ng-enter.ng-enter-active {
+ *   opacity:1;
+ * }
+ * ```
+ *
+ * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
+ * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
+ * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
+ *
+ * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
+ *
+ * ```css
+ * /&#42; now the element will fade out before it is removed from the DOM &#42;/
+ * .fade.ng-leave {
+ *   transition:0.5s linear all;
+ *   opacity:1;
+ * }
+ * .fade.ng-leave.ng-leave-active {
+ *   opacity:0;
+ * }
+ * ```
+ *
+ * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
+ *
+ * ```css
+ * /&#42; there is no need to define anything inside of the destination
+ * CSS class since the keyframe will take charge of the animation &#42;/
+ * .fade.ng-leave {
+ *   animation: my_fade_animation 0.5s linear;
+ *   -webkit-animation: my_fade_animation 0.5s linear;
+ * }
+ *
+ * @keyframes my_fade_animation {
+ *   from { opacity:1; }
+ *   to { opacity:0; }
+ * }
+ *
+ * @-webkit-keyframes my_fade_animation {
+ *   from { opacity:1; }
+ *   to { opacity:0; }
+ * }
+ * ```
+ *
+ * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
+ *
+ * ### CSS Class-based Animations
+ *
+ * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
+ * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
+ * and removed.
+ *
+ * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
+ *
+ * ```html
+ * <div ng-show="bool" class="fade">
+ *   Show and hide me
+ * </div>
+ * <button ng-click="bool=true">Toggle</button>
+ *
+ * <style>
+ * .fade.ng-hide {
+ *   transition:0.5s linear all;
+ *   opacity:0;
+ * }
+ * </style>
+ * ```
+ *
+ * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
+ * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
+ *
+ * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
+ * with CSS styles.
+ *
+ * ```html
+ * <div ng-class="{on:onOff}" class="highlight">
+ *   Highlight this box
+ * </div>
+ * <button ng-click="onOff=!onOff">Toggle</button>
+ *
+ * <style>
+ * .highlight {
+ *   transition:0.5s linear all;
+ * }
+ * .highlight.on-add {
+ *   background:white;
+ * }
+ * .highlight.on {
+ *   background:yellow;
+ * }
+ * .highlight.on-remove {
+ *   background:black;
+ * }
+ * </style>
+ * ```
+ *
+ * We can also make use of CSS keyframes by placing them within the CSS classes.
+ *
+ *
+ * ### 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;/
+ *   transition: 1s linear all;
+ *   opacity:0;
+ * }
+ * .my-animation.ng-enter-stagger {
+ *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
+ *   transition-delay: 0.1s;
+ *
+ *   /&#42; As of 1.4.4, this must always be set: it signals ngAnimate
+ *     to not accidentally inherit a delay property from another CSS class &#42;/
+ *   transition-duration: 0s;
+ * }
+ * .my-animation.ng-enter.ng-enter-active {
+ *   /&#42; standard transition styles &#42;/
+ *   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 $animate. However, the restrictions surrounding this
+ * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
+ * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were 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
+ *
+ * window.requestAnimationFrame(function() {
+ *   //stagger has reset itself
+ *   $animate.leave(kids[5]); //stagger index=0
+ *   $animate.leave(kids[6]); //stagger index=1
+ *
+ *   $scope.$digest();
+ * });
+ * ```
+ *
+ * Stagger animations are currently only supported within CSS-defined animations.
+ *
+ * ### The `ng-animate` CSS class
+ *
+ * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
+ * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
+ *
+ * Therefore, animations can be applied to an element using this temporary class directly via CSS.
+ *
+ * ```css
+ * .zipper.ng-animate {
+ *   transition:0.5s linear all;
+ * }
+ * .zipper.ng-enter {
+ *   opacity:0;
+ * }
+ * .zipper.ng-enter.ng-enter-active {
+ *   opacity:1;
+ * }
+ * .zipper.ng-leave {
+ *   opacity:1;
+ * }
+ * .zipper.ng-leave.ng-leave-active {
+ *   opacity:0;
+ * }
+ * ```
+ *
+ * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
+ * the CSS class once an animation has completed.)
+ *
+ *
+ * ### The `ng-[event]-prepare` class
+ *
+ * This is a special class that can be used to prevent unwanted flickering / flash of content before
+ * the actual animation starts. The class is added as soon as an animation is initialized, but removed
+ * before the actual animation starts (after waiting for a $digest).
+ * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
+ *
+ * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
+ * into elements that have class-based animations such as `ngClass`.
+ *
+ * ```html
+ * <div ng-class="{red: myProp}">
+ *   <div ng-class="{blue: myProp}">
+ *     <div class="message" ng-if="myProp"></div>
+ *   </div>
+ * </div>
+ * ```
+ *
+ * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
+ * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
+ *
+ * ```css
+ * .message.ng-enter-prepare {
+ *   opacity: 0;
+ * }
+ *
+ * ```
+ *
+ * ## JavaScript-based Animations
+ *
+ * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
+ * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
+ * `module.animation()` module function we can register the animation.
+ *
+ * Let's see an example of a enter/leave animation using `ngRepeat`:
+ *
+ * ```html
+ * <div ng-repeat="item in items" class="slide">
+ *   {{ item }}
+ * </div>
+ * ```
+ *
+ * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
+ *
+ * ```js
+ * myModule.animation('.slide', [function() {
+ *   return {
+ *     // make note that other events (like addClass/removeClass)
+ *     // have different function input parameters
+ *     enter: function(element, doneFn) {
+ *       jQuery(element).fadeIn(1000, doneFn);
+ *
+ *       // remember to call doneFn so that angular
+ *       // knows that the animation has concluded
+ *     },
+ *
+ *     move: function(element, doneFn) {
+ *       jQuery(element).fadeIn(1000, doneFn);
+ *     },
+ *
+ *     leave: function(element, doneFn) {
+ *       jQuery(element).fadeOut(1000, doneFn);
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
+ * greensock.js and velocity.js.
+ *
+ * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
+ * our animations inside of the same registered animation, however, the function input arguments are a bit different:
+ *
+ * ```html
+ * <div ng-class="color" class="colorful">
+ *   this box is moody
+ * </div>
+ * <button ng-click="color='red'">Change to red</button>
+ * <button ng-click="color='blue'">Change to blue</button>
+ * <button ng-click="color='green'">Change to green</button>
+ * ```
+ *
+ * ```js
+ * myModule.animation('.colorful', [function() {
+ *   return {
+ *     addClass: function(element, className, doneFn) {
+ *       // do some cool animation and call the doneFn
+ *     },
+ *     removeClass: function(element, className, doneFn) {
+ *       // do some cool animation and call the doneFn
+ *     },
+ *     setClass: function(element, addedClass, removedClass, doneFn) {
+ *       // do some cool animation and call the doneFn
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * ## CSS + JS Animations Together
+ *
+ * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular,
+ * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
+ * charge of the animation**:
+ *
+ * ```html
+ * <div ng-if="bool" class="slide">
+ *   Slide in and out
+ * </div>
+ * ```
+ *
+ * ```js
+ * myModule.animation('.slide', [function() {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       jQuery(element).slideIn(1000, doneFn);
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * ```css
+ * .slide.ng-enter {
+ *   transition:0.5s linear all;
+ *   transform:translateY(-100px);
+ * }
+ * .slide.ng-enter.ng-enter-active {
+ *   transform:translateY(0);
+ * }
+ * ```
+ *
+ * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
+ * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
+ * our own JS-based animation code:
+ *
+ * ```js
+ * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element) {
+*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
+ *       return $animateCss(element, {
+ *         event: 'enter',
+ *         structural: true
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
+ *
+ * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
+ * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
+ * data into `$animateCss` directly:
+ *
+ * ```js
+ * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element) {
+ *       return $animateCss(element, {
+ *         event: 'enter',
+ *         structural: true,
+ *         addClass: 'maroon-setting',
+ *         from: { height:0 },
+ *         to: { height: 200 }
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * Now we can fill in the rest via our transition CSS code:
+ *
+ * ```css
+ * /&#42; the transition tells ngAnimate to make the animation happen &#42;/
+ * .slide.ng-enter { transition:0.5s linear all; }
+ *
+ * /&#42; this extra CSS class will be absorbed into the transition
+ * since the $animateCss code is adding the class &#42;/
+ * .maroon-setting { background:red; }
+ * ```
+ *
+ * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
+ *
+ * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
+ *
+ * ## Animation Anchoring (via `ng-animate-ref`)
+ *
+ * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
+ * structural areas of an application (like views) by pairing up elements using an attribute
+ * called `ng-animate-ref`.
+ *
+ * Let's say for example we have two views that are managed by `ng-view` and we want to show
+ * that there is a relationship between two components situated in within these views. By using the
+ * `ng-animate-ref` attribute we can identify that the two components are paired together and we
+ * can then attach an animation, which is triggered when the view changes.
+ *
+ * Say for example we have the following template code:
+ *
+ * ```html
+ * <!-- index.html -->
+ * <div ng-view class="view-animation">
+ * </div>
+ *
+ * <!-- home.html -->
+ * <a href="#/banner-page">
+ *   <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
+ * </a>
+ *
+ * <!-- banner-page.html -->
+ * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
+ * ```
+ *
+ * Now, when the view changes (once the link is clicked), ngAnimate will examine the
+ * HTML contents to see if there is a match reference between any components in the view
+ * that is leaving and the view that is entering. It will scan both the view which is being
+ * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
+ * contain a matching ref value.
+ *
+ * The two images match since they share the same ref value. ngAnimate will now create a
+ * transport element (which is a clone of the first image element) and it will then attempt
+ * to animate to the position of the second image element in the next view. For the animation to
+ * work a special CSS class called `ng-anchor` will be added to the transported element.
+ *
+ * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
+ * ngAnimate will handle the entire transition for us as well as the addition and removal of
+ * any changes of CSS classes between the elements:
+ *
+ * ```css
+ * .banner.ng-anchor {
+ *   /&#42; this animation will last for 1 second since there are
+ *          two phases to the animation (an `in` and an `out` phase) &#42;/
+ *   transition:0.5s linear all;
+ * }
+ * ```
+ *
+ * We also **must** include animations for the views that are being entered and removed
+ * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
+ *
+ * ```css
+ * .view-animation.ng-enter, .view-animation.ng-leave {
+ *   transition:0.5s linear all;
+ *   position:fixed;
+ *   left:0;
+ *   top:0;
+ *   width:100%;
+ * }
+ * .view-animation.ng-enter {
+ *   transform:translateX(100%);
+ * }
+ * .view-animation.ng-leave,
+ * .view-animation.ng-enter.ng-enter-active {
+ *   transform:translateX(0%);
+ * }
+ * .view-animation.ng-leave.ng-leave-active {
+ *   transform:translateX(-100%);
+ * }
+ * ```
+ *
+ * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
+ * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
+ * from its origin. Once that animation is over then the `in` stage occurs which animates the
+ * element to its destination. The reason why there are two animations is to give enough time
+ * for the enter animation on the new element to be ready.
+ *
+ * The example above sets up a transition for both the in and out phases, but we can also target the out or
+ * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
+ *
+ * ```css
+ * .banner.ng-anchor-out {
+ *   transition: 0.5s linear all;
+ *
+ *   /&#42; the scale will be applied during the out animation,
+ *          but will be animated away when the in animation runs &#42;/
+ *   transform: scale(1.2);
+ * }
+ *
+ * .banner.ng-anchor-in {
+ *   transition: 1s linear all;
+ * }
+ * ```
+ *
+ *
+ *
+ *

+ * ### How is the element transported?
+ *
+ * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
+ * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
+ * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
+ * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
+ * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
+ * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
+ * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
+ * will become visible since the shim class will be removed.
+ *
+ * ### How is the morphing handled?
+ *
+ * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
+ * what CSS classes differ between the starting element and the destination element. These different CSS classes
+ * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
+ * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
+ * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
+ * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
+ * the cloned element is placed inside of root element which is likely close to the body element).
+ *
+ * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
+ *
+ *
+ * ## Using $animate in your directive code
+ *
+ * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application?
+ * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
+ * imagine we have a greeting box that shows and hides itself when the data changes
+ *
+ * ```html
+ * <greeting-box active="onOrOff">Hi there</greeting-box>
+ * ```
+ *
+ * ```js
+ * ngModule.directive('greetingBox', ['$animate', function($animate) {
+ *   return function(scope, element, attrs) {
+ *     attrs.$observe('active', function(value) {
+ *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
+ *     });
+ *   });
+ * }]);
+ * ```
+ *
+ * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
+ * in our HTML code then we can trigger a CSS or JS animation to happen.
+ *
+ * ```css
+ * /&#42; normally we would create a CSS class to reference on the element &#42;/
+ * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
+ * ```
+ *
+ * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
+ * possible be sure to visit the {@link ng.$animate $animate service API page}.
+ *
+ *
+ * ## Callbacks and Promises
+ *
+ * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
+ * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
+ * ended by chaining onto the returned promise that animation method returns.
+ *
+ * ```js
+ * // somewhere within the depths of the directive
+ * $animate.enter(element, parent).then(function() {
+ *   //the animation has completed
+ * });
+ * ```
+ *
+ * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
+ * anymore.)
+ *
+ * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
+ * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
+ * routing controller to hook into that:
+ *
+ * ```js
+ * ngModule.controller('HomePageController', ['$animate', function($animate) {
+ *   $animate.on('enter', ngViewElement, function(element) {
+ *     // the animation for this route has completed
+ *   }]);
+ * }])
+ * ```
+ *
+ * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.)

+ *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are

+ *
+ *   The whitelist for URL sanitization of attribute values is configured using the functions

+ *   `$compileProvider`}.
+ *
+ *   The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.
