final paper

@haosharon @jhelbert 

i wrote up a bunch of stuff that will hopefully be useful for the paper. i made it a pull request so you guys can more easily comment on specific lines.

we can use as little or as much of this as you guys want, but **by Tuesday's class, I'd really appreciate it if you could read this over, comment on anything you guys have opinions on, and come with some ideas for the final paper** such as stuff you dis/liked about this, what you guys want to write, etc...
