// Class : ActorNode
// Description : Like a physical node, but with a little more. The
// actornode assumes responsibility for its own
// transform, and changes in its own PhysicsObject will
// be reflected as transforms. This relation goes both
// ways; changes in the transform will update the
// object's position (shoves).
