In which Meredith gets along with people

Yet another discussion with my adviser that didn't turn into a fight. I am, in a word, amazed.

(And he was even being critical this time: he pointed out a general use-case for QBE which my machine-learning library supports but my SQL syntax doesn't. So now I get to dive back into the grammar and fix that, but it won't be hard -- and it's the right time to do it, since I haven't really gotten started implementing ranking yet. So, look for that update sometime around the end of this month/beginning of next.)
