[vtkusers] Python wrapping

[David Gobbi]

Hi John,

You can use CMake to do the wrapping for you.  All you should
have to do is use the attached CMakeLists.txt file, search-and-replace
'vtkMyClass' with whatever your class is called, put it in the
same directory as your class, and run cmake.  CMake will ask you
where VTK build directory is, and should do all wrapping automatically
from there.

Do not try to use swig, sip, or any other wrapping tools with your class!
Even if you succeeded, you wouldn't be able to use your class together
with the other VTK wrapped classes.

 - David
