[vtkusers] vtkConnectivityFilter

[SM Rolfe]

Hi David,
Thanks! The vtkCleanPolyData filter solves the connectivity issue. It also
looks like it's reducing the resolution of the output mesh significantly.
If it's only deleting the repeated points, I don't think this should be
occurring?
Thanks,
Sara
