[Paraview] Minimal setup for coprocessing in a Fortran solver

[Renato Elias]

lol, It just worked \o/

I thought coprocessor would open ParaView to make the visualization
interactively but it produced the vtkPolydata files and stored them in the
directory where I called TestPVCoProcessing program. I guess it's working
as expected :0)

Well, thanks again!

Renato.
