Neat! I'll fix the facet problem soon. I should also note that you can add new functions to Exhibit without having to check out the code base. What Johan did was adding that last chunk of code to
http://simile.mit.edu/repository/exhibit/branches/2.0/src/webapp/api/scripts/data/functions.js which can actually be added outside the code base. Just include your code after you include exhibit-api.js (only for version 2.0, which hasn't been released).
