sun.py renamed to sunrise.py
Formatting tweaks for comet.py
Created angles.py

Checks for easily seen planets and Moon being close to each other and
if they are getting closer or further away.
Could extend this to calculate times of closest approach.
Created files.py to manage the .astro folder

We'll keep useful data here, like comets, space stations, and maybe
sunrise/sunset/twilight data
First version of sun.py
SunEvents checkpoint
sun.py now uses SortedCollection
