[vtk] obj delete in Python

[David Gobbi]

Hi Randy,

The only way to guarantee that any python object is deleted
it to remove all references to it.  And that's all that that
'del' does, it un-binds the python vtkPoints object from the
name 'pts', and hence removes a reference from vtkPoints object.

Use pts.DebugOn() to see if the VTK object is deleted
when you expect.
