missing code in triangulate()? no longer deleting last three vertices

[nosarious]

While trying to troubleshoot a problem, I downloaded your code again instead of using my modified stuff, and it wouldn't work, but in a different way.

comparing older files, I noticed the following lines are missing from the end of your code:

//erase the last three triangles
vertices.erase(vertices.end()-1);
vertices.erase(vertices.end()-1);
vertices.erase(vertices.end()-1);

these would go right before the 'return ntri' and caused all sorts of errors and almost made me cry.

I feel these lines are kinda-sorta important...?
