/** A CCSprite subclass that is bound to a physics body.
 It works with:
 - Chipmunk: Preprocessor macro CC_ENABLE_CHIPMUNK_INTEGRATION should be defined
 - Objective-Chipmunk: Preprocessor macro CC_ENABLE_CHIPMUNK_INTEGRATION should be defined
 - Box2d: Preprocessor macro CC_ENABLE_BOX2D_INTEGRATION should be defined

 Features and Limitations:
 - Scale and Skew properties are ignored.
 - Position and rotation are going to updated from the physics body
 - If you update the rotation or position manually, the physics body will be updated
 - You can't enble both Chipmunk support and Box2d support at the same time. Only one can be enabled at compile time
 * @js NA
 * @lua NA
