Patch Set 4: No score

I've inlined a bunch of comments. I didn't really play with it much to be honest. Mostly just trying out the user interface and going over the diffs.

As an aside, I think the strings/messages may need some rewording but that can be addressed later.

Oh, there were also some unused NLS message warnings in my console. Please either a) use them or b) delete them. ;)
