Yes, but I have two issues with it: It uses jittering to try to avoid 
degeneracies and so is not truly robust. It is very, very difficult to work with 
as a library; it was written to be a standalone program, so there are global 
variables and other such nonsense floating about. For N-D, it's pretty much the 
only game in town; however, for 2-D, there are much better options.
