Paper: BCE: Berkeley's Common Scientific Compute Environment for Research and Education (Dav Clark)

Please accept this paper for now - it's in terrible shape, but I promise I'll clean it up. I just wanted to be sure to send a pull request for *something* in time for the deadline (and I'm teaching at an R bootcamp now... oops).
I added a relatively low-quality citation. I'll see if Brian can dig something else up, but we could also drop this...
