[Paraview] Multiple paraview instances in MPI standalone mode

[Amy Squillacote]

If you're wanting to run ParaView in parallel, you probably want to run 
in client/server mode. Start pvserver with multiple processors, and then 
attach a pvclient to it. To try it out on your single machine (and 
create a 2-processor server), do the following.

mpirun -np 2 pvserver
pvclient
