-/**
- * 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 Hammer.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 Hammer.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 Hammer.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 {Hammer.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 Hammer.detection.current. This is the current
- * detection session. 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 Hammer.detection.current.name
- *
- * @readonly
- * @param {Hammer.Instance} inst
- * the instance we do the detection for
- *
- * @readonly
- * @param {Object} startEvent
- * contains the properties of the first gesture detection in this session.
- * Used for calculations about timing, distance, etc.
- *
- * @readonly
- * @param {Object} lastEvent
- * contains all the properties of the last gesture detect in this session.
- *
- * after the gesture detection session has been completed (user has released the screen)
- * the Hammer.detection.current object is copied into Hammer.detection.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 Hammer.gestures object, it is auto registered
- * at the setup of the first Hammer instance. You can also call Hammer.detection.register
- * manually and pass your gesture object as a param
- *
