Hangry

Yelp client (around 12 hours to complete):

- [x] Table rows should be dynamic height according to the content height
- [x] Custom cells should have the proper Auto Layout constraints
- [x] Search bar should be in the navigation bar (doesn't have to expand to show location like the real Yelp app does).
- [x] You can use the default UISwitch for on/off states
- [x] Clicking on the "Search" button should dismiss the filters page and trigger the search w/ the new filter settings.
- [x] The filters you should actually have are: category, sort (best match, distance, highest rated), ~~radius (meters)~~, deals (on/off).
- [ ] Radius filter should expand as in the real Yelp app
- [ ] The filters table should be organized into sections as in the mock.
