* Custom gestures
* ==============================
*
* Gesture object
* --------------------
* The object structure of a gesture:
*
* { name: 'mygesture',
* index: 1337,
* defaults: {
* mygesture_option: true
* }
* handler: function(type, ev, inst) {
* // trigger gesture event
* inst.trigger(this.name, ev);
* }
* }
* @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.
