[vtkusers] Tutorial Step1: NotImplementedError

Hi Darya,

The concrete implementation for vtkPolyDataMapper is
vtkOpenGLPolyDataMapper.  The NotImplementedError probably means that the
vtkRenderingOpenGLPython.so module is not loading, because it is the module
that contains vtkOpenGLPolyDataMapper.

I cannot be sure why this module is not loading on your system, but you can
try loading it manually from python:

  >>> from vtkRenderingOpenGLPython import *
  >>> mapper = vtkOpenGLPolyDataMapper()
  >>> print mapper.GetClassName()
  >>> from vtkRenderingCore import *
  >>> mapper2 = vtkPolyDataMapper()
  >>> print mapper2.GetClassName()
