Summary: To date, our sample project was lacking. There is still a lot of work that can be done to improve, but, this is a step in the right direction. Here are the changes in this commit: 1. The project is written in Swift. 2. Created new CollectionView (via [IGListKit](https://github.com/instagram/iglistkit)), making it very easy to add new examples. 3. New examples for basic layouts, and including/excluding layouts on the fly. Here's a video!
