These azimuth/inclination gates are useful to me, and I'd like to continue to experiment with them. Given probability from Z/X/Y basis measurements, azimuth should equal acos(2 * probZ)and inclination should equal atan(2 * probY, 2 * probX). Per more common conventions for spherical to Cartesian coordinate conversion, as per the Wikipedia articles, this should be an intuitive way to think of (de-)constructing states from Pauli Z/X/Y basis probability expectation.

I'll add a unit test before merging, to show and test the intended application.

It's possible that I'm missing the application of Heisenberg's uncertainty principle to this case, or I've just screwed up the implementation. For now, this doesn't work, and I need to rethink it.
