Create documentation for RAVEN package

Currently there is no current documentation for how the ligo-raven package works or how to use the functions within it.

This could be done using sphinx (see gwcelery for an example, gwcelery docs), using docstrings with the already existing functions, and showing some examples of using python scripts/command line options.

Current Status:

• Set up sphinx and basic pages
• Write up descriptions of functions in docstrings
• Write up examples
• Write up descriptions of online/offline searches with examples
• Set up on readthedocs to make public
