+ Singleton that handles all the touch events.
+ The dispatcher dispatches events to the registered TouchHandlers.
+ There are 2 different type of touch handlers:
+   - Standard Touch Handlers
+   - Targeted Touch Handlers
+ 
+ The Standard Touch Handlers work like the CocoaTouch touch handler: a set of touches is passed to the delegate.
+ 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).
+ 
+ Firstly, the dispatcher sends the received touches to the targeted touches.
+ These touches can be swallowed by the Targeted Touch Handlers. If there are still remaining touches, then the remaining touches will be sent
+ to the Standard Touch Handlers.
