[Paraview] exporting VRML files with python script

[Utkarsh Ayachit]

You have to write each file individually. However, you can do it just
a few lines without copy-pasting as follows:

exporters = servermanager.createModule("exporters")
vrml = exporters.VRMLExporter()

for d in range(3):
  vrml.FileName = "/tmp/%d.vrml" % d
  vrml.View = GetActiveView()
  vrml.Write()
