Over the last week, Lisa and I have made several changes to the format of the data, so now the older records in the MongoDB database are poorly formatted. We need to clear all the old records and then re-import from OpenSIS and Moodle, and then regenerate the fake data. We will probably need to this repeatedly over the next few months (if development continues) so I'm adding this in as a function in /home/das/.mongorc.js, so we can re-use it.
