There was a bug by which even though a new Extra was getting created, it wasn't having its instance variables set. Whoops. Also, Extra::Extra.who now exists.
Might as well remove the markdown README, it'll just get out of date. Made a factory for a small User class. We'll need it for some tests, but we don't want to give one away with extraextra. read_all_about_it was just returning a hash rather than an Extra object, so we made it do that.
Should be able to set the candy host and port. Baller.
