60/** CCTouchDispatcher.
61 Singleton that handles all the touch events.
62 The dispatcher dispatches events to the registered TouchHandlers.
63 There are 2 different type of touch handlers:
64 - Standard Touch Handlers
65 - Targeted Touch Handlers
66
67 The Standard Touch Handlers work like the CocoaTouch touch handler: a set of touches is passed to the delegate.
68 On the other hand, the Targeted Touch Handlers only receive 1 touch at the time, and they can "swallow" touches (avoid the propagation of the event).
69
70 Firstly, the dispatcher sends the received touches to the targeted touches.
71 These touches can be swallowed by the Targeted Touch Handlers. If there are still remaining touches, then the remaining touches will be sent
72 to the Standard Touch Handlers.
