make physics based animation effects part of the animation engine

Wiring up and creating required classes for physics based
animation effects to be part of the animation engine.

Creating a new animation node AnimationPhysicsNode
for physics based animation effects and PhysicsAnimation
class that inherits the NumberAnimation in the animation
factory.
