[vtkusers] deriving my own class from vtkActor

[K.R.Subramanian]

I concur.. I used to be able to derive classes from vtkActor (to add an id for instance)
in vtk3.2.
Sometime back (in response to a similar query), when I tried it again under 4.0, it
wouldnt render
the actor at all.  I had tried to modify the Cone example to test this out...
