Summary:
Started work on the plane to get this moving since #418 is up and ready to land. We'll likely need to spend some time fleshing out the API of this, and I think I'll split it up into a couple different PRs once ready for review. Putting this up now to get early feedback.
This adds an auto-diffing section controller as outlined in #38. There are several key parts:
- Subclass a new section controller `IGListAutoSectionController` (naming wip)
- Connect a data source
- Implement the data source methods that do 3 things:
- Given a top-level object, transform it into an array of **diffable** view models
- Given a view model, return a cell
- Given a view model, return a size for a cell
- A new protocol for the cell `IGListBindable` so that we can control when the cell is updated w/ the view model.
- The most important part of this is that it unlocks moving and reloading a cell, which you can't do w/ `UICollectionView`
- [ ] Unit test `reloadObjects:`

Summary:
Batch updates are complicated b/c its unknown when the update block will actually execute. When executing the block, we want to collect inserts/deletes/reloads/moves (item and section). Allow mutations to happen synchronously outside of the update block.
Tracking state will also help with the auto-diff where we need to allow re-entrant updates.

Summary:
Removing the assert and handling `nil` section controllers. This wont effect Swift code which demands a non-optional section controller, but Objective-C is more nuanced. There is evidence that some callers do not have a default state and are returning `nil`.
Unfortunately this will [OOB here](https://github.com/Instagram/IGListKit/blob/master/Source/Internal/IGListSectionMap.m#L63) if using the original `objects` array provided by the data source. Instead we prune the array, only allowing in objects that have a matching section controller.

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

Summary:
I was able to build a unit test that reproduces the issue. We can avoid the crash by simply returning `nil` when accessing a cell while working range events are being vended.
There is definitely something weird going on here though. When debugging `cellForItemAtIndexPath:` I found:
```
(lldb) po indexPath
<NSIndexPath: 0xc000000000000516> {length = 2, path = 5 - 0}
(lldb) po [[self collectionView] numberOfSections]
11
```
So in theory we should be fine, right? But when I continue I get
```
