- After a discussion on usability the following changes have been made:
> All SceneObject and SceneObject-behavior collision callbacks are named "onCollision()" & "onEndCollision()".
> All Scene and Scene-behavior collision callbacks are named "onSceneCollision()" & "onEndSceneCollision()".

The two differences are that the SceneObject collision callbacks only reference the object being collided with and the collision details whereas the Scene collision callbacks reference both objects that are colliding and the collision details.
