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.
