   * 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>
 * ```
 * ----------
 *
 * ### 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.
