Celestial Programming : Long Term Precession - Vondrak et al.

This is the implementation of the long term Precession algorithm from New precession expressions, valid for long time intervals which is valid for "several thousand centuries" surrounding J2000. As opposed to the IAU 2006 model which is considered valid only for a few centuries surrounding J2000.

The output below is the computed values for the test case presented in the paper.
