Don Cross ae0946bd47 Implemented C versions of Astronomy_CombineRotation, Astronomy_InverseRotation. ...

Beginning to implement functions for converting among the
following four orientation systems:

- EQJ: equatorial J2000
- EQD: equatorial of date
- ECL: ecliptic J2000
- HOR: horizontal

Starting with some basic functions for manipulating rotation matrices.
Astronomy_CombineRotation multiplies two rotation matrices to obtain
a third that combines their effects in order. I will use these for
combining a precession matrix and a nutation matrix, to obtain a
rotation matrix that can convert between EQJ and EQD.

Astronomy_InverseRotation will allow converting in either direction
between two orientations.
