Yes @ssaumitra, if we have the enumerator, then it's a matter of calling a
`count` to get the number of triangles. So, let's just got for
`TriangleEnumerator ` in the library. As for exposing the `Triad`, there's not
need to do so. `Triad` actually extends `Tuple3`, so I would say to simply
return `DataSet<Tuple3>`.
