Display perfect/good/bad fit dorms

I started working on the javascript for this. Next steps:

- reformat the `dorms` array to have the same format as `selections`
- add logic for determining perfect/good/bad fit
  - perfect = everything matches
  - good = up to two criteria don't match
  - bad = more than two criteria don't match (or gender doesn't match?)
- add logic for adding dots to the displayed table (if nothing is checked, don't display them)
