This more than likely will only run on Chrome at the moment. Sorry :(.
Make sure this is run from a web server. Otherwise Chrome will complain with a cross origin request error when trying to load local coffeescript files.
This run from within the project directory should do the trick:
python -m SimpleHTTPServer
You can then visit: http://localhost:8000/index.html
Tests can be run by visiting: http://localhost:8000/test.html
