[vtkusers] Converting vtkPolyData to vtkUnstructuredGrid for Exodus Export

[Thompson, David C]

Well, copying is going to be required no matter what because
vtkUnstructuredGrid stores cells in a single vtkCellArray while
vtkPolyData has a different cell array for each type of primitive.
That said, vtkCleanUnstructuredGrid probably does some extra
work you're not interested in (i.e., point merging).

I'm doing this from straight VTK code.  I did look at the
vtkCleanUnstructuredGrid code in Paraview and it looks like it does it
does lots of copying.

    Thanks,
