[vtkusers] Writing a file

[Darshan Pai]

Yes it is a vtk File . I hope there were no changes to the vtk file format
? Because this vtk file was generated from VTK 4.4 . Since we are moving
everything to a newer version of VTK , I want to make sure older files do
not need to be reworked on

Regards
Darshan
