[vtkusers] Python and vtkMultiProcessController

[Charles Law]

Stan,

The MultiProcessController and port classes have not been integrated with 
the wrapped interpreters.  I have made examples that use Tcl in all the MPI 
processes, but the initialization of the controller (SingleMethod, 
MultipleMethod, ...) was integrated with the initialization of Tcl.  The 
details of this approach need to be worked out before it gets integrated 
into the VTK release.

Charles.
