[Paraview] Importing paraview.simple from python

[Zhou, Fangyi]

Thanks to previous emails I have managed to get it running on Linux, but I have the similar problem on mac

% export DYLD_FALLBACK_FRAMEWORK_PATH=/Applications/paraview.app/Contents/Frameworks
% export DYLD_FALLBACK_LIBRARY_PATH=/Applications/paraview.app/Contents/Libraries
% export DYLD_LIBRARY_PATH=/Applications/paraview.app/Contents/Libraries/
% export PYTHONPATH=/Applications/paraview.app/Contents/Python:/Applications/paraview.app/Contents/Python/vtk:/Applications/paraview.app/Contents/Libraries

Home-brew python:

% which python
/usr/local/bin/python
% python
