Another set of magnetic tile polyhedra. This time, three different trapezohedra.

I used this resource to define the kite and dihedral angles, but the hexagonal and heptagonal did not work out (and I believe the octagonal also has issues). Fixing them is on my to do list. I plan to write a script that actually generates them from the antriprisms.
