[Paraview] Getting Python object reference to representation/proxy of each object loaded in Paraview.

[Olumide]

Hi,

I'd like to get the reference to representation or proxy (not sure which 
I need) to each object loaded in Paraview via Python.

The big picture: I'd like to rotate each object stepwise about its 
vertical axis, turntable style. I'm trying to produce an animation. 
Orbiting the camera will merely circle all objects which isn't what I want.

Thanks,
