[Paraview] Singleton vtkObject multiple SMProxies

[Biddiscombe, John A.]

Further to my last message. I see that you've overridden the getProxy in the SMAdaptiveOptionsProxy class. This is good. They can all reuse the same underlying proxy. I tried using a singleton SMproxy itself - I see your way is better - no connection ID problem.

Now I just need to get the filter to take one as a param...

Thanks for the clues. I think I'm getting close.
