Ryan Nystrom e2c2d3dcec Vertical UICollectionViewLayout supporting inline sections (take 2)
Summary:
Working on porting our collection view layout to IGListKit. I'm doing this because its a solid layout, and we just finished preparing it to work with inline sections. It is designed to work in tandem with IGListKit, so we're adding it.

This is still a WIP as I add more tests, but I'd love as much feedback as possible.

Aside from the glob of header documentation, this has the following features:

- Infinite sections that each have infinite items. Sections and items can fall inline. When they break the width of their container they will fall on the next row.
- Sections can have their own insets, line spacing, and interitem spacing.
- Sticky header support! When you use headers, it will always newline the section.
- Maximum width with a border decoration view
  - Use this to pinch in your content on larger devices

Followup to #423

- [ ] ~~Move decoration view support to delegate~~ removed
- [x] Unit test changing [top y sticky inset](https://coveralls.io/builds/9977284/source?filen
Closes https://github.com/Instagram/IGListKit/pull/484
