This code requires GTS (http://gts.sourceforge.net) to build.

Usage:
fast_delaunay num_pts exclusion_radius > point_list.txt

This will insert points into the [0-1]x[0-1] square, separated by at
least exclusion_radius from each other, until either num_pts points
have been added, or there is no more free space to insert a point.
