Another New Animation Scene Object

I’ve created another new animation scene object. This one uses the same advanced animation controller code that was recently integrated with the mesh object. The new scene object can be used to animate any child object in the scene, i.e. the position and rotation of a camera, light, etc. Linear or spline (slerp, Catmull-Rom, etc.) interpolation can be used. In addition, the keyframes can have regular or irregular intervals. Animation data can be easily imported from an animation set in a mesh file.
