[AstroPy] Back to Python. Precession and PhysConst code.

[Wayne Watson]

It's been quite awhile since I used python, but I was digging around on 
PC for something on precession, and discovered some code for it, 
prec.py.   Here are the first few lines.

#!/usr/bin/env python
"""

"""
import RO.PhysConst
from euler import *
...
...

It dies on RO.PhysConst when I run it.  Probably a further difficulty is 
the euler reference.
I have the code for RO.PhysConst.py

What needs to be done to successfully execute prec.py?
