[Paraview] python scripting

[Pat Marion]

For PYTHONPATH, try removing the last /paraview components from the path,
so you're setting:   /Applications/ParaView.app/Contents/Python

Also add /Applications/ParaView.app/Contents/Libraries to PYTHONPATH and
DYLD_LIBRARY_PATH.  Note, that is DYLD not LD.  You don't need to add the
Contents/bin directory to DYLD_LIBRARY_PATH, and you don't need to add
DYLD_LIBRARY_PATH to PATH, and you don't need to add PYTHONPATH to PATH.


In summary, ParaView uses both pure python modules and c extension
modules.  The pure python modules are in Contents/Python, and the c
extension modules are in Contents/Libraries.  Both these paths should be on
PYTHONPATH (or append sys.path at the top of your main script).  The c
extenion modules have dependencies on dynamic libraries which are located
in Contents/Libraries, so Contents/Libraries this needs to be in the
DYLD_LIBRARY_PATH.
