An astronomy library for precessing coordinates between epochs and converting between topocentric (z = up, x = east), ecliptic (heliocentric), equatorial (celestial), and galactic coordinate systems. Vectors are 3 dimensional with magnitude 1, representing a point on the unit sphere. Includes generic 3 vector rotation code.
