Mayor Hunter v1!

Below is my take on mayor hunter. Few notes:

* I haven't used foursquare in a while, so i was unsure if there was any other requirements besides more check ins compared to the resident mayor. If it is time sensitive, like check ins during the past 30 days, this could be easily tweaked by adding a param to one of the foursquare API calls

* this is built for iOS 7.0+ for tall iPhones only (iPhone 5, 5S). Mainly because i didn't want to spend more time on UI for 2 different screen sizes

* Foursquare API wouldn't let me specify only certain fields, so this is totally getting more data then needed

* The foursquare SDK requires the foursquare mobile app installed in order for Mayor Hunter to get the access token. If there was another nicer way I probably missed it.

* Ran out of time, but usually for any sort of sorting I would place it on a background thread so the UI thread wont lag. I have a 5S but didn't notice any as it is now.

* I never ever make commits this big, I promise :)

Thank you guys again for having me yesterday, and feel free to comment on this PR or call me if you have any questions.

Best,

heh, yes but i just noticed its in the wrong spot. It should be inside the for loop not right outside
