Hi @ssaumitra! Thanks a lot for the pull request, it looks good.
I was thinking, since this algorithm not only counts but actually
enumerates all triangles, we could have 2 library methods, `TriangleCounter`
and `TriangleEnumerator`. They would basically use the same algorithm
internally, but the first would return the number of triangles, while the
second would return a `DataSet` of `Tuple3`, containing the vertex IDs that
form triangles. What do you think?
