The normal examples are meant to be run standalone so just run them
outside the editor.  Tkinter and the vtk*Interactor loop dont gel well
and you will end up with difficulty.  OTOH, the ivtk classes were
designed to be used in a non-intrusive manner when using the Python
interpreter or Tkinter (and hence idle).
