Compatibility with astropy.units

[cgobat]

The a_u object type is not currently compatible with astropy.units. Adding this functionality would greatly enhance this package for use across the physical sciences, and would certainly be very nice to have, given that this package's perhaps most notable use case is in astronomy & astrophysics.

My initial thought is that the most straightforward way to do this will be to make a_u a subclass of astropy.units.Quantity.

The astropy-units-compatibility branch has been updated with basic support for mathematical operations between instances of a_u and instances of astropy.units.Quantity and astropy.units.Unit.
