[Paraview] How to get a vtkClientServerID of a already created vtkobject in dataserver

[Utkarsh Ayachit]

Typically, all proxies that represent VTK filters have an "Input" 
property. Look any proxy definition in 
Server/ServerManager/Resources/filters.xml. You will have to add an 
"Input" property to your cutter proxy as well (If you are using the 
Cutter provided by paraview, it already has an input property). Now on 
the client side, I am assuming you have access to the reader proxy as 
well as the cutter proxy. To set the reader as the input to the cutter 
one simply does:

vtkSMInputProperty::SafeDownCast(
   cutterProxy->GetProperty("Input"))->AddProxy(readerProxy);

This will setup the pipeline on the data server (or where were the vtk 
objects might actually be).

Generally speaking, one does not have access to the vtkClientServerID in 
the VTK filters created on the servers. vtkSMProxy provides API to 
access the IDs for the VTK objects it stands for:
vtkSMProxy::GetNumberOfIDs() and vtkSMProxy::GetID(unsigned int). Thus, 
the ServerManager and ParaView client are aware of and can access the IDs.
