NEW: math/qhull port

Can somebody commit this: http://trac.macports.org/projects/macports/ticket/11990 NEW: qhull 2003.1 New port for the qhull package. Qhull computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspace intersection about a point, furthest-site Delaunay triangulation, and furthest-site Voronoi diagram. The software runs in 2-d, 3-d, 4-d, and higher dimensions. Qhull implements the Quickhull algorithm for computing the convex hull. It handles roundoff errors from floating point arithmetic. Qhull also computes volumes, surface areas, and approximations to the convex hull. -- Mark
