[vtkusers] Python wrappers for new extensions developed with C++

[David Gobbi]

Hi Jordi,

If you were able to make libvtkLocalPython.so, then all you should have 
left to do is set the pythonpath.

The file libvtkLocalPython.so is a python extension module, so it must 
be in the PYTHONPATH before you can load it.  The PYTHONPATH isn't only 
for .py files.

"
export PYTHONPATH=./bin/
"

Note that usually you should use the full absolute path, instead of a 
relative path starting with "."

 - David
