Code Cleanup: Updated Documentation

Some more non code-based changes.  I updated some of the doc comments to follow the new PEP-8 standard of 100-character lines in the python files.  I also fixed one of the HTML comments so that the HTML would be valid.  Finally, I fixed a couple grammar issues in the README.

I realize this is most likely fluff stuff, but code will be in the next pull-request I promise!
