Python + VTK + NumPy expert/examples

[David Gobbi]

Hi Greg,

I have written some tools to help with this.  I can email them
to you if you want.

The tools are three python classes:
vtkImageExportToArray:   export an image to a NumPy array
vtkImageImportFromArray: import an image from a NumPy array
vtkMatrixProxy: has the 'look and feel' of a 4x4 Numeric array,
                but it shares storage with a vtkMatrix4x4

Also, it is possible to pass a python string to most vtk methods
which require a void * (only in VTK 2.4 and above, though). 

 - David
