[vtkusers] curvatures

[Philipp.Batchelor]

Hi,
following the question on the computation of curvatures, I have
put my class on the web. It is a PolyDataToPolyDataFilter taking triangulated 
surfaces as input, and adding a Scalar corresponding
to curvature at the vertices. It can certainly  be extended, so I'll
welcome any suggestions:

(I used latex2html, so it might look more than what it is).
