New formula for Triangle

Triangle is a library and command-line tool that generates triangular meshes
through Delunay Triangulation with exact arithmetic.  Such meshes are suitable
for use in such applications as Finite Element analysis.

Also included is a X11 program called `showme` which is useful for visualizing
triangular meshes.
