+/**
+ @class
+
+ Base class for all gesture recognizers. Handles low-level touch and state
+ management, and provides some utility methods and some required methods all
+ gesture recognizers are expected to implement.
+
+ ## Overview
+
+ Gestures coalesce multiple touch events to a single higher-level gesture
+ event. For example, a tap gesture recognizer takes information about a
+ touchstart event, a few touchmove events, and a touchend event and uses
+ some heuristics to decide whether or not that sequence of events qualifies
+ as a tap event. If it does, then it will notify the view of the higher-level
+ tap events.
+
+ Gesture events follow the format:
+
+ * *[GESTURE_NAME]* Start - Sent when a gesture has gathered enough information
+ to begin tracking the gesture
+
+ * *[GESTURE_NAME]* Change - Sent when a gesture has already started and has
+ received touchmove events that cause its state to change
+
+ * *[GESTURE_NAME]* End - Sent when a touchend event is received and the gesture
+ recognizer decides that the gesture is finished.
+
+ * *[GESTURE_NAME]* Cancel - Sent when a touchcancel event is received.
+
+ There are two types of gestures: Discrete and Continuous gestures. In contrast
+ to continuous gestures, discrete gestures don't have any change events. Rather,
+ the end event is the only one that gets sent to the view.
+
+ ## Usage
+
+ While you wouldn't use Em.Gesture directly, all its subclasses implement the
+ same API. For example, to implement pinch on a view, you implement one or more
+ of the pinch events. For example:
+
+ var myView = Em.View.create({
+ pinchStart: function(recognizer) {
+ this.$().css('background','red');
+ },
+
+ pinchChange: function(recognizer) {
+ var scale = recognizer.get('scale');
+ this.$().css('scale',function(index, value) {
+ return recognizer.get('scale') * value
+ });
+ },
+
+ pinchEnd: function(recognizer) {
+ this.$().css('background','blue');
+ },
+
+ pinchCancel: function(recognizer) {
+ this.$().css('background','blue');
+ }
+ });
+
+ pinchStart(), pinchEnd() and pinchCancel() will only get called once per
+ gesture, but pinchChange() will get called repeatedly called every time
+ one of the touches moves.
+
+ ## Customizing Gesture Recognizers
+
+ Some of the gesture recognizers include properties that can be customized by
+ the user for a specific instance of a view. For example, a pan gesture defaults
+ to being a one-finger gesture, but in some scenarios, it must be defined as a
+ two-finger gesture. In that case, you can override defaults by specifying an
+ Options hash.
+
+ var myView = Em.View.create({
+ panOptions: {
+ numberOfRequiredTouches: 2
+ }
+ });
+
+ ## Creating Custom Gesture Recognizers
+
+ Em.Gesture also defines an API which its subclasses can implement to build
+ custom gestures. The methods are:
+
+ * **didBecomePossible** - Called when a gesture enters a possible state. This
+ means the gesture recognizer has accepted enough touches to match
+ the number of required touches. You would usually initialize your state
+ in this callback.
+
+ * **eventWasRejected** - Called if a view returns false from a gesture event.
+ This callback allows you to reset internal state if the user rejects
+ an event.
+
+ * **shouldBegin** - Allows a gesture to block itself from entering a began state.
+ This callback will continuously be called as touches move until it begins.
+
+ * **shouldEnd** - Allows a gesture to block itself from entering an ended state.
+ This callback gets called whenever a tracked touch gets a touchEnd event.
+
+ * **didBegin** - Called when the gesture enters a began state. Called before the
+ view receives the Start event on continuous gestures.
+
+ * **didChange** - Called when the gesture enters a changed state, and when one of the
+ touches moves. Called before the view receives the Change event on continuos gestures.
+
+ * **didEnd** - Called when the gesture enters an ended state. Called before the
+ view receives the End event.
+
+ * **didCancel** - Called when the gesture enters a cancelled state. Called before the
+ view receives the Cancel event on continuos gestures.
+
+ In all the callbacks, you can use the `touches` protected property to access the
+ touches hash. The touches hash is keyed on the identifiers of the touches, and the
+ values are the jQuery.Event objects. You can also access the length property to inspect
+ how many touches are active, this is mostly useful in shouldBegin since every other
+ callback can assume that there are as many active touches as specified in the
+ numberOfRequiredTouches property.
+
+ ## Discrete vs Continuous Gestures
+
+ There are two main classes of gesture recognizers: Discrete and Continuous
+ gestures. Discrete gestures do not get Start, Change nor Cancel events sent,
+ since they represent a single, instantaneous event, rather than a continuous
+ motion. If you are implementing your own discrete gesture recognizer, you must
+ set the gestureIsDiscrete property to yes, and Em.Gesture will adapt its behavior.
+
+ Discrete gestures use the shouldEnd callback to either accept or decline the gesture
+ event. If it is declined, then the gesture will enter a Cancelled state.
