wip/py-quaternionic 0.2.0 NetBSD

This module subclasses numpy's array type, interpreting the array as an array of quaternions, and accelerating the algebra using numba. This enables natural manipulations, like multiplying quaternions as `a*b`, while also working with standard numpy functions, as in `np.log(q)`. There is also basic initial support for symbolic manipulation of quaternions by creating quaternionic arrays with sympy symbols as elements, though this is a work in progress
