Contains static files that can be retrieved by the web server and sent to clients.

• editor.coffee: The music editor code, now written in CoffeeScript. For those unfamiliar, CoffeeScript is a handy language that compiles to JavaScript. It's like JS, but more scalable and without the idiosyncracies.
• editor.less: The stylesheets describing the mixer layout. Some other things are crammed in there as well, which will be taken out eventually. This is written in LESS, which is like CoffeeScript in that it compiles to another language (CSS, in this case), but unlike CS in that it is completely backwards-compatible. In fact, this file is still pure CSS at the moment. This is likely to change soon.
