[vtkusers] Closing holes in PolyData

[Goodwin Lawlor]

Here's the outline of how to do it:
1. Use vtkFeatureEdges to get the boundary edges
2. Use vtkStripper to to convert lines to polylines
3. Use this trick to convert polylines to polygons:
    vtkPolyData pd
    pd SetPoints [stripper GetPoints]
    pd SetPolys [stripper GetLines]
4. Use vtkTriangleFilter or the GLU version to triangulate
5. Use vtkAppendFilter to add the the pieces back to the original
6. Use vtkCleanPolyData to delete coincident points

I have a filter (somewhere...) that does this- I'll have a look for it.
