[vtkusers] Deleting unknown object: vtkObject - vector of pointers?

[Bill Lorensen]

Your member variable does not have to be a smartpointer. If it is not,
you'll have to Register it on a Set. And UnRegister on destruction.
 If you use the vtkSetObject macro, it will do the proper
register/unregister. You will still have to UnRegister in the the
descturcotr if it is not null.
