* @class
* CCControl is inspired by the UIControl API class from the UIKit library of

*
* The goal of CCControl is to define an interface and base implementation for
* preparing action messages and initially dispatching them to their targets when
* certain events occur.
*
* To use the CCControl you have to subclass it.
