Create simple example documentation

[cjcodeproj]

The tools need some simple usage documentation that covers the command line tools, and Python shell invocation.

The documentation should follow Python conventions, and they should probably be in RST format. I will also need to figure out Python conventions for bundling extra documentation with a package.

Additional notes:

• The documentation should probably be in .rst format, since it's a Python convention
• I'm following the conventions from "Structuring Your Project" from "The Hitchhiker's Guide To Python", which so far is the only resource I've found that discusses supplemental documentation in a Python module.
• So far, I have not found any documentation on how the Python build/setup process handles document files. Do they become manages?

One more addendum:

The documentation should be bundled with the code, but I'm not 100% concerned with the presentation. If the documentation files are readable on GitHub through the web interface, then I'm fine with that. Building usable documentation files suitable for installation on a host can be focused on a later date.

Closing Notes:

• Writing in RST feels tedious. Going to need to investigate more tools for linting and validating.
• Will need to write tests to check for trailing whitespace on .rst files.
