   *   defaults: {
   *     mygesture_option: true

   *   }
   * }

   * @param   {String}    name
   * this should be the name of the gesture, lowercase
   * it is also being used to disable/enable the gesture per instance config.
   *
   * @param   {Number}    [index=1000]
   * the index of the gesture, where it is going to be in the stack of gestures detection
   * like when you build an gesture that depends on the drag gesture, it is a good
   * idea to place it after the index of the drag gesture.
   *
   * @param   {Object}    [defaults={}]
   * the default settings of the gesture. these are added to the instance settings,
   * and can be overruled per instance. you can also add the name of the gesture,
   * but this is also added by default (and set to true).
   *
   * @param   {Function}  handler
   * this handles the gesture detection of your custom gesture and receives the
   * following arguments:
   *
   *      @param  {Object}    eventData
   *      event data containing the following properties:
   *          timeStamp   {Number}        time the event occurred
   *          target      {HTMLElement}   target element
   *          touches     {Array}         touches (fingers, pointers, mouse) on the screen
   *          pointerType {String}        kind of pointer that was used. matches ionic.Gestures.POINTER_MOUSE|TOUCH
   *          center      {Object}        center position of the touches. contains pageX and pageY
   *          deltaTime   {Number}        the total time of the touches in the screen
   *          deltaX      {Number}        the delta on x axis we haved moved
   *          deltaY      {Number}        the delta on y axis we haved moved
   *          velocityX   {Number}        the velocity on the x
   *          velocityY   {Number}        the velocity on y
   *          angle       {Number}        the angle we are moving
   *          direction   {String}        the direction we are moving. matches ionic.Gestures.DIRECTION_UP|DOWN|LEFT|RIGHT
   *          distance    {Number}        the distance we haved moved
   *          scale       {Number}        scaling of the touches, needs 2 touches
   *          rotation    {Number}        rotation of the touches, needs 2 touches *
   *          eventType   {String}        matches ionic.Gestures.EVENT_START|MOVE|END
   *          srcEvent    {Object}        the source event, like TouchStart or MouseDown *
   *          startEvent  {Object}        contains the same properties as above,
   *                                      but from the first touch. this is used to calculate
   *                                      distances, deltaTime, scaling etc
   *
   *      @param  {ionic.Gestures.Instance}    inst
   *      the instance we are doing the detection for. you can get the options from
   *      the inst.options object and trigger the gesture event by calling inst.trigger
   *
   *
   * Handle gestures
   * --------------------
   * inside the handler you can get/set ionic.Gestures.detectionic.current. This is the current
   * detection sessionic. It has the following properties
   *      @param  {String}    name
   *      contains the name of the gesture we have detected. it has not a real function,
   *      only to check in other gestures if something is detected.
   *      like in the drag gesture we set it to 'drag' and in the swipe gesture we can
   *      check if the current gesture is 'drag' by accessing ionic.Gestures.detectionic.current.name
   *
   *      readonly
   *      @param  {ionic.Gestures.Instance}    inst
   *      the instance we do the detection for
   *
   *      readonly
   *      @param  {Object}    startEvent
   *      contains the properties of the first gesture detection in this sessionic.
   *      Used for calculations about timing, distance, etc.
   *
   *      readonly
   *      @param  {Object}    lastEvent
   *      contains all the properties of the last gesture detect in this sessionic.
   *
   * after the gesture detection session has been completed (user has released the screen)
   * the ionic.Gestures.detectionic.current object is copied into ionic.Gestures.detectionic.previous,
   * this is usefull for gestures like doubletap, where you need to know if the
   * previous gesture was a tap
   *
   * options that have been set by the instance can be received by calling inst.options
   *
   * You can trigger a gesture event by calling inst.trigger("mygesture", event).
   * The first param is the name of your gesture, the second the event argument
   *
   *
   * Register gestures
   * --------------------
   * When an gesture is added to the ionic.Gestures.gestures object, it is auto registered
   * at the setup of the first ionic.Gestures instance. You can also call ionic.Gestures.detectionic.register
   * manually and pass your gesture object as a param

/**
 * @ngdoc page
 * @name tap
 * @module ionic
 * @description
 * On touch devices such as a phone or tablet, some browsers implement a 300ms delay between
 * the time the user stops touching the display and the moment the browser executes the
 * click. This delay was initially introduced so the browser can know whether the user wants to
 * double-tap to zoom in on the webpage.  Basically, the browser waits roughly 300ms to see if
 * the user is double-tapping, or just tapping on the display once.
 *
 * Out of the box, Ionic automatically removes the 300ms delay in order to make Ionic apps
 * feel more "native" like. Resultingly, other solutions such as
 * [fastclick](https://github.com/ftlabs/fastclick) and Angular's
 * [ngTouch](https://docs.angularjs.org/api/ngTouch) should not be included, to avoid conflicts.
 *
 * Some browsers already remove the delay with certain settings, such as the CSS property
 * `touch-events: none` or with specific meta tag viewport values. However, each of these
 * browsers still handle clicks differently, such as when to fire off or cancel the event
 * (like scrolling when the target is a button, or holding a button down).
 * For browsers that already remove the 300ms delay, consider Ionic's tap system as a way to
 * normalize how clicks are handled across the various devices so there's an expected response
 * no matter what the device, platform or version. Additionally, Ionic will prevent
 * ghostclicks which even browsers that remove the delay still experience.
 *
 * In some cases, third-party libraries may also be working with touch events which can interfere
 * with the tap system. For example, mapping libraries like Google or Leaflet Maps often implement
 * a touch detection system which conflicts with Ionic's tap system.
 *
 * ### Disabling the tap system
 *
 * To disable the tap for an element and all of its children elements,
 * add the attribute `data-tap-disabled="true"`.
 *
 * ```html
 * <div data-tap-disabled="true">
 *     <div id="google-map"></div>
 * </div>
 * ```
 *
 * ### Additional Notes:
 *
 * - Ionic tap  works with Ionic's JavaScript scrolling
 * - Elements can come and go from the DOM and Ionic tap doesn't keep adding and removing
 *   listeners
 * - No "tap delay" after the first "tap" (you can tap as fast as you want, they all click)
 * - Minimal events listeners, only being added to document
 * - Correct focus in/out on each input type (select, textearea, range) on each platform/device
 * - Shows and hides virtual keyboard correctly for each platform/device
 * - Works with labels surrounding inputs
 * - Does not fire off a click if the user moves the pointer too far
 * - Adds and removes an 'activated' css class
 * - Multiple [unit tests](https://github.com/driftyco/ionic/blob/master/test/unit/utils/tap.unit.js) for each scenario
 *

/*

 IONIC TAP
 ---------------
 - Both touch and mouse events are added to the document.body on DOM ready
 - If a touch event happens, it does not use mouse event listeners
 - On touchend, if the distance between start and end was small, trigger a click
 - In the triggered click event, add a 'isIonicTap' property
 - The triggered click receives the same x,y coordinates as as the end event
 - On document.body click listener (with useCapture=true), only allow clicks with 'isIonicTap'
 - Triggering clicks with mouse events work the same as touch, except with mousedown/mouseup
 - Tapping inputs is disabled during scrolling

/**
 * @ngdoc page
 * @name keyboard
 * @module ionic
 * @description
 * On both Android and iOS, Ionic will attempt to prevent the keyboard from
 * obscuring inputs and focusable elements when it appears by scrolling them
 * into view.  In order for this to work, any focusable elements must be within
 * a [Scroll View](http://ionicframework.com/docs/api/directive/ionScroll/)
 * or a directive such as [Content](http://ionicframework.com/docs/api/directive/ionContent/)
 * that has a Scroll View.
 *
 * It will also attempt to prevent the native overflow scrolling on focus,
 * which can cause layout issues such as pushing headers up and out of view.
 *
 * The keyboard fixes work best in conjunction with the
 * [Ionic Keyboard Plugin](https://github.com/driftyco/ionic-plugins-keyboard),
 * although it will perform reasonably well without.  However, if you are using
 * Cordova there is no reason not to use the plugin.
 *
 * ### Hide when keyboard shows
 *
 * To hide an element when the keyboard is open, add the class `hide-on-keyboard-open`.
 *
 * ```html
 * <div class="hide-on-keyboard-open">
 *   <div id="google-map"></div>
 * </div>
 * ```
 *
 * Note: For performance reasons, elements will not be hidden for 400ms after the start of the `native.keyboardshow` event
 * from the Ionic Keyboard plugin. If you would like them to disappear immediately, you could do something
 * like:
 *
 * ```js
 *   window.addEventListener('native.keyboardshow', function(){
 *     document.body.classList.add('keyboard-open');
 *   });
 * ```
 * This adds the same `keyboard-open` class that is normally added by Ionic 400ms after the keyboard
 * opens. However, bear in mind that adding this class to the body immediately may cause jank in any
 * animations on Android that occur when the keyboard opens (for example, scrolling any obscured inputs into view).
 *
 * ----------
 *
 * ### Plugin Usage
 * Information on using the plugin can be found at
 * [https://github.com/driftyco/ionic-plugins-keyboard](https://github.com/driftyco/ionic-plugins-keyboard).
 *
 * ----------
 *
 * ### Android Notes
 * - If your app is running in fullscreen, i.e. you have
 *   `<preference name="Fullscreen" value="true" />` in your `config.xml` file
 *   you will need to set `ionic.Platform.isFullScreen = true` manually.
 *
 * - You can configure the behavior of the web view when the keyboard shows by setting
 *   [android:windowSoftInputMode](http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode)
 *   to either `adjustPan`, `adjustResize` or `adjustNothing` in your app's
 *   activity in `AndroidManifest.xml`. `adjustResize` is the recommended setting
 *   for Ionic, but if for some reason you do use `adjustPan` you will need to
 *   set `ionic.Platform.isFullScreen = true`.
 *
 *   ```xml
 *   <activity android:windowSoftInputMode="adjustResize">
 *
 *   ```
 *
 * ### iOS Notes
 * - If the content of your app (including the header) is being pushed up and
 *   out of view on input focus, try setting `cordova.plugins.Keyboard.disableScroll(true)`.
 *   This does **not** disable scrolling in the Ionic scroll view, rather it
 *   disables the native overflow scrolling that happens automatically as a
 *   result of focusing on inputs below the keyboard.

 *
 * The above creates an instance of minErr in the example namespace. 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.

 * 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
              instantiate, by using explicit annotation style
              (see script.js for details)

       </div>

       <div ng-controller="BadController">
           I can add: {{a}} + {{b}} =  {{ a+b }}

           <p>The controller could not be instantiated, due to relying
              on automatic function annotations (which are disabled in
              strict mode). As such, the content of this section is not

     * The `angular.module` is a global place for creating, registering and retrieving Angular
     * modules.
     * All modules (angular core or 3rd party) that should be available to an application must be
     * registered using this mechanism.

     * When passed two or more arguments, a new module is created.  If passed only one argument, an
     * existing module (the name passed as the first argument to `module`) is retrieved.
     *
     *
     * # Module
     *
     * A module is a collection of services, directives, controllers, filters, and configuration information.
     * `angular.module` is used to configure the {@link auto.$injector $injector}.
     *
     * ```js
     * // Create a new module
     * var myModule = angular.module('myModule', []);
     *
     * // register a new service
     * myModule.value('appName', 'MyCoolApp');
     *
     * // configure existing services inside initialization blocks.
     * myModule.config(['$locationProvider', function($locationProvider) {
     *   // Configure existing providers
     *   $locationProvider.hashPrefix('!');
     * }]);
     * ```
     *
     * Then you can create an injector and load your modules like this:
     *
     * ```js
     * var injector = angular.injector(['ng', 'myModule'])
     * ```
     *
     * However it's more likely that you'll just use
     * {@link ng.directive:ngApp ngApp} or
     * {@link angular.bootstrap} to simplify this process for you.
     *
     * @param {!string} name The name of the module to create or retrieve.
     * @param {!Array.<string>=} requires If specified then new module is being created. If
     *        unspecified then the module is being retrieved for further configuration.
     * @param {Function=} configFn Optional configuration function for the module. Same as
     *        {@link angular.Module#config Module#config()}.
     * @returns {module} new module with the {@link angular.Module} api.

/**
 * @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."
 *
 * <div class="alert alert-success">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.</div>
 *
 * To use jQuery, simply load it before `DOMContentLoaded` event fired.
 *
 * <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
 * jqLite; they are never raw DOM references.</div>
 *
 * ## Angular's jqLite
 * jqLite provides only the following jQuery methods:
 *
 * - [`addClass()`](http://api.jquery.com/addClass/)
 * - [`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()`
 * - [`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 or selectors
 * - [`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/)
 * - [`removeData()`](http://api.jquery.com/removeData/)
 * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
 * - [`text()`](http://api.jquery.com/text/)
 * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
 * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
 * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
 * - [`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.
 *
 * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
 * @returns {Object} jQuery object.
