[vtkusers] Callbacks from the render window interacor / interactorstyle

[Vidyadhar]

Hi,
I do not know exactly how to do this in Python but vtkInteractorStyle has 
two events - InteractionEvent and EndInteractionEvent. InteractionEvent can 
be used to contiously update camera position (but it can slow down things). 
If you can add observer for one/both these events and then get query 
camera's position then you can update the edit box.
