Summary: Adding an example using self sizing cells (`estimatedSize` API of `UICollectionViewFlowLayout`) both in code and from cells in nibs. I assume cells in storyboards would follow the same AL design patterns as nibs, so I left out storyboards.  Fixes #149 - [x] All tests pass. Demo project builds and runs. - [x] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/master/CONTRIBUTING.md) Closes https://github.com/Instagram/IGListKit/pull/176 Differential Revision: D4156409 Pulled By: rnystrom fbshipit-source-id: b0b6d0cc8f4a575ff9963d66bc0df605843d47fe
