Branched the git repo and cleaned out all the multi-schema stuff from master. Also made a lot of progress on creating a user-friendly approach to generating a new play file and a new schema, so that users can follow along in the Instructions file and just type an id and a title and get their play file. I have one outstanding question on the Oxygen board; if I can't do what I want to the way I want to, I have a workaround in mind.
