[vtkusers] Python .egg packaging and installation with VTK v6.1.0

[David Gobbi]

Hi Adamos,

In order to use the modules, all of the VTK DLLs must be in the PATH
(or you can copy them into the same directory as the .pyd files).

As far as I could tell I just needed to build the 'INSTALL' upon setting the 'VTK_INSTALL_PYTHON_MODULE_DIR' variable under CMake to the 'lib\site-packages' directory of my Python installation. I should mention that during  'Install' all the 'bin', 'include', etc directories end up under 'Program Files'. However, when trying to import VTK through python under the Python installation I just installed it in, the import fails with a:
