[Paraview] Python Programmable Filter: Get Filename of Import filter

[Markus Fuger]

Hi Pat,

Thank you for your hint! Unfortunately I would need one more step:
The reason is that the last filter after the while loop will return a
vtkFileSeriesReader where I can't find or access the file information
property.
Looking at the doxygen documentation it in principle should have, but
perhaps not everything is wrapped into the ParaView VTK module.
