Functionality complete; demo needs work

Completed README documentation.
Tweaked README formatting for optimal display on GitHub; BitBucket's
    Markdown support is less robust.

Will now proceed to flesh out the demo somewhat in order to provide
    more testing of newly-modified (or -added) functionality.  Once
    that's done, I will tag release v0.0.0.
