NEW: math/py-triangle (part of Ultimaker Cura + dependencies by Evandro Rathke)

Hi ports@,

This is part of the big effort Evandro Rathke is taking to port
Ultimaker Cura and its dependencies.

Original port by him with some tweaks by me.

mat/py-triangle
Python binding to the triangle library

The port does not include tests on the pypi tarball. I tested manually
the examples on the website and everything seems ok on amd64

ok to import ?
