Added my libtriangles, plus the "examples" folder
Cleaned up the examples folder
Changes examples/example.libtriangles.scad to test_libtriangles.scad
Added licensing stuff.
Removed test_libtriangles. I was under the mistaken impression is provided a set of examples, so you could see at a glance the result of the code. This doesn't really need a test function.
