b71c346f66 Amend swiftlint to work with older installations
Summary:
![image](https://cloud.githubusercontent.com/assets/15193942/26492070/41f53338-420a-11e7-8ed6-f5d9872338c4.png)

Noticed an issue when trying to build the examples project that I couldn't because of the Swiftlint build phase (see the image above)

As it turns out in between the version I have installed (0.16.1) and the latest (0.19.0) they've made it so you can drop `lint` from the command (which is the default task).

I see two options really:
1. We add `lint` to the command which at least lets older versions of Swiftlint compile the project without making changes to run phases. It's worth noting that this means that certain (newer) rules won't be detected.
2. We add a way of detecting if they have an older version (likely by comparing the output of `$(swiftlint version)` to the version we know it works on. And display a more appropriate message and not fail the build.

Happy to discuss this

Changes from last PR:
- Deleted the shared SwiftLint folder, incl. all files (On the plus side, did this in the quest to get this PR in https://github.com/realm/SwiftLint/pull/1513)
- Changed the build script such that it runs the user's `HomeBrew` installation of SwiftLint instead of the local copy

Integrates SwiftLint into DangerBot.

32a566d7c9 Regen docs for 3.0
Summary:
~~Land after #661, #730 and D5031184~~

Rebuild the docs from script. Couple notes:

- Went from 100% to 99%, does that matter? Script output says
  - > 99% documentation coverage with 2 undocumented symbols
  - Looks like `NS_SWIFT_NAME` throws documentation for a loop on `IGListDiffOption` and `IGListExperiment`
- Swift names are different, will that be a problem?

40625f8ff9 Swift name annotations
Summary:
This adds `NS_SWIFT_NAME` annotations to all public API's to provide cleaner integration into Swift:

- Removes the need to prefix classes in Swift code, instead rely on Swift module name spacing
- Adds more argument labels to C function API's like `IGListDiff([], [], .equality)` => `ListDiff(oldArray: [], newArray: [], option: .equality)`

While this is a large API change it should be as easy as:

- Find and replace `(IGList)([^K])` to `List$2` in Xcode with a scope set to Swift
- Build and follow compiler's auto fix corrections for C API's or any missed renames

I have not updated the documentation to reflect this yet, I am totally willing to do so but before I sink that amount of time into it I wanted to see if the Instagram team is even open to this change!

a4e5ad862e Move section index to property
Summary:
This pull request removes the `sectionForSectionController:` method from the `IGListCollectionContext` protocol so that the protocol is exclusively for presentation methods.

This should not add new functionality, but rather makes the index directly accessible on the section controllers themselves. This change makes sense because at no time will there be an update to the list that the list adapter is unaware of and so it will always be able to set and update any indexes for a section controller that has changed.

49bf24693d Demo for dependency injection and announcing changes
Summary:
Created a new demo that shows off how to:

- Inject dependencies to section controllers
  - Objects shared between section controllers
  - Things that aren't the core "object"
- Announce changes from the VC that make their way to the section controllers
  - Without calling updates

2ac81d4c37 Generics are now necessary on the IGListBindingSectionController object
Summary:
PR #602 added generics to `IGListBindingSectionController` in the ObjC code but did not update the Swift Examples. Swift fails to compile without any form of generic specification.

623ff2a8a8 Container size doesnt use content inset, add new APIs
Summary:
The content inset of a collection view can change at any time (as it does with our refresh control) and isn't a good measure of the container size. I don't want to totally remove that API though, so I changed the default behavior, added an insets API, and also added the functionality of the original in a new API.

This makes sizes much more deterministic.

a15ea08614 Move section controller mutation API to object provided in update block
Summary:
We constantly have random bugs pop up when mutations are made outside of a batch update. This change restricts the mutation API to a batch context object (which is just an `IGListAdapter`) so they can only be done **inside an update block**.

- Fixed open source project
- Confirmed open source examples build
- Updated all of Instagram.app to use this API
- Changelog breaking changes entry

79348164a7 Auto diffing section controller
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:`
- [x] Add

a7855d15ac consistent use of finall class
Summary:
You are already using `final class` as the default swift declaration as I guess most people agree this is best practice for classes you are not planning to inherit from :) So I just made the example code more consistent.

I will not add much more reasoning to why, other than open source projects like this is a _big_ inspirations and starting ground to play with swift for new develoeprs joining the iOS community. Nuding them to ask the right questions (composition vs inheritance) early could only be a good thing (?)

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
