[vtkusers] Snycing interactors: interactor styles

[Gerrick Bivins]

Thanks for the reply.
I was able to do it by:
1) Adding mouseinteractionevent for each interactor
2) in the interactorevent, get the current interactors camera
3) update the cameras of the other interactors
4) update light and clipping range on the other cameras
5) call OnMouseMove() of the selected camera.

Probably not that elegant but I wanted to get going on it.

Thanks for the input.
