Actually, this is the part of the voronoi structure I find most useful
and would absolutely love to have in CGAL.  From a graphics and
generative design standpoint having a Polyhedron_3 dual would be a
huge benefit.  The thing I've had the hardest time doing with CGAL is
getting the voronoi structure up to the point where it intersects with
the convex hull.  Are there efficient ways to derive this from the
Delaunay_triangulation_3 class?
