[vtkusers] python wrapper for vtkPartialVolumeModeller

[Dr. Roman Grothausmann]

Dear Cory,


Recently I wanted to use Your vtkPartialVolumeModeller in VTK-6.1.0 with python 
(as before). However, the VTK directory structure has changed and I could not 
find a directory to put it into to compile. Either vtkBoxClipDataSet.h or 
vtkDataSetSurfaceFilter.h are not found. There is a note in the CMakeLists.txt 
that they used to be in the same directory but that was changed.
What could I do to get a python wrapping for vtkPartialVolumeModeller again in VTK6?

Thanks for any help or hints.
Roman
