I made some more changes for VTK 6.0. Most of the changes work with VTK
5.8 and 6.0, but a few don't and those are conditionaly compiled. I
started with versions that Kathleen modified for VTK 6.0 and added
conditional compiles for code that wouldn't work with VTK 5.8.

The types of changes made were:

1) filter->SetInput(vtkDataObject);
   filter->AddInput(vtkDataObvect);
   filter->RemoveInput(vtkDataObvect);

     to

   filter->SetInputData(vtkDataObject);
   filter->AddInputData(vtkDataObvect);
   filter->RemoveInputData(vtkDataObvect);

2) filter1->SetInput(filter2->GetOutput());

     to

   filter1->SetInputConnection(filter2->GetOutputPort());
