Readme to markdown

First of all Jesse I've got to thank you so much, both for this awesome code (which I use a lot of places) and the fact you influenced a lot of the folks who influenced me. Happy to see you've moved over to GitHub, and if I can ever help with how you use it let me know.

To that end I took a crack at reformatting your README to Markdown so it displays more cleanly and readably on your site page. Let me know if it works for you. 

Again, thanks so much.
