Detailed Description

A set of triangles stored on a Grid.

The Grid must carry Vertices in Cartesian coordinates and a (2,1) Skeleton (dimension 2, depth 1) as triangles. The (2,2) Skeleton describes the sets of triangles.

The positions field of this triangle set is a 1D array of vector<index_t> which describes the triangle indices make up a triangle set. This class supports computation of quantities such as defined at http://en.wikipedia.org/wiki/Differential_geometry_of_curves
