Regarding names for Vframe, I feel we can use the 'unnamed' approach.

As far as vframe generation using scene object. I am a little confused on the approach @fitze mentioned.
It is just that we define a vframe with a shape. I have been trying to keep it super-general, not knowing even if rbodies exist or not.
Just give the numerical data to a vframe, a shape and it gets done. 

But even If we want to generate vframes from Scene automatically, how are we going to attach shapes to a particular vframe.? I am not sure on that one.

Also It will complicate things more If we are thinking of the child-frames for a VFrame type thing.
I am also not sure whether we should keep nested frames,(i.e. one frame child to another vframe).
