Add tests to artists app.
Add social fields to artist model.
Merge branch '_development_kashif' of https://github.com/kalail/hypestarter into _development_colby
Side Bar: Added Tweet functionality. Facebook doesn't work perfectly yet.  Also have another comment square….will be used to show an artists point total? Social engagement? Idk.
Added a gif for developing functionality -- need something that shows when & where tweets about a specific artist are coming from and occurring.
Top Tweeters code added.  It's hard coded since we don't have users yet.
