The problem with that is it'll make for some neigh unreadable and 
unmaintainable javascript (imo) code. I'd like to be able to change the 
groupings at a whim, which would mean a lot of crazy add/remove code.

I'm not sure I can do what I want in javascript since the bindings are 
missing a few crucial parts. I was trying it out just to learn the bindings. 
I can just as easily (or probably easier, since I'm much more familiar with 
it) do it in C++.
