Work in progress: Python demo of searching for pair longitudes.

Browse Source 
Started work on a Python demo for finding when the moon
reaches relative longitudes with other solar system bodies
that are multiples of 30 degrees. It is not finished yet,
but getting close.

Added operator overloads for the Python Time class so
that times can be compared against each other.
This makes it easier to sort a list of times, for example.
