AnimationBase is an abstract base for classes that define the animation type for a Geometry.
It creates an AnimationState, which is what defines the current animation state for each Mesh/SubMesh
It also creates an AnimationController, which is what influences the state inside AnimationState (for example a
timeline based controller, a physics based controller, etc)
