5fe27d8809 Add debug dump scripts
Summary:
Got a little time on the plane to mess around with this idea. Very much want comments on this! Some questions:

- We should probably compile out parts of this using `#if DEBUG`.
  - Should I compile out all of the description methods?
  - Maybe I wrap the entire debug files w/ `#if DEBUG ... #endif` so none of it is loaded?
- ryanolsonk I used [FLEX](https://github.com/Flipboard/FLEX/blob/master/Classes/Utility/FLEXHeapEnumerator.m) for searching the heap, lmk if you see any problems w/ this
  - Its lifted w/ only a few changes for my specific needs (including comments 😂)
  - Chalk us up for using [another bit](https://github.com/Instagram/IGListKit/blob/master/Source/Internal/IGListAdapterProxy.m#L77-L82) of your code
- Added a basic test so that the basics of this work and coverage doesn't tank
  - Anything else I should test?
- Is there more data we should be dumping?
- I have to track batch update state on the updater in order to dump it. If this seems dan

073fc073e0 Prevent duplicate item deletes and drop reload collisions
Summary:
a415ef5552 exposed a bug in `UICollectionView` where its state gets corrupted when deleting the same index path more than once in a single batch update block. This resulted crashes like

a415ef5552 Prevent a crash when inserting the same index twice, re-open of #616
Summary:
Original comment:

If you insert or delete into the same index twice **and** update your data source to reflect those changes, we will squash the insert/delete into a single update because we're using `NSSet` internally.

This becomes very apparent when multiple updates are coalesced.

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

Fixes #392

4dec244416 Add item-level moves to IGListCollectionContext
Summary:
Adding an API to do item-level (cell) moves on the collection view. This complicates things a little bit because of all the issues that moving sections have while in batch updates (e.g. simultaneous animation UICV bugs). Thankfully we use pretty strict types so the compiler does most of the work for us.

Closes #145

- [x] Tests build and pass
- [x] Add `IGListBatchUpdateData` tests to check moves during
  - [x] ~~Moving within a reloaded section (no op)~~ can't reload sections
  - [x] Moving within a deleted section (no op)
  - [x] Moving within a moved section (convert section ops to delete+insert)
  - [x] Moving an index path that is also reloaded (convert to delete+insert path)
- [x] Add move unit tests to `IGListAdapterUpdater`
- [x] Add move unit tests to `IGListReloadDataUpdater` (mostly for code coverage...)
- [x] Add move unit tests to `IGListStackedSectionController`
- [x] Add `CHANGELOG.md` entry for 3.0.0

5cd771b546 Added Subspec for Diffing
Summary:
So the main Podspec file now has two Subspecs, `Diffing` and for lack of better name `Default`. `Diffing` is purely the files within the common directories (used for Diffing, if in the future we support MacOS NSCollectionView then this may need changing). `Default` depends on `Diffing` but also adds all the non-common files.

To use it via CocoaPods, nothing changes. You `import IGListKit` and you will only have access to the files in the pod you use. (So if you use `IGListKit/Diffing` in your Podfile, then you will only get access to the diffing files). If you do a manual installation, or I assume via Carthage, then you will need to import the correct header file (either `IGListDiffKit.h` or `IGListKit.h` depending on what you want).

Turns out CocoaPods creates it's own umbrella header (unless you tell it otherwise) meaning our ones are unused by it.

Just to confirm `IGListKit` in your Podfile will give you everything, only if you add `/Diffing` will you "opt-out" o

19d4f9d1f7 Added compatibility header
Summary:
- Added IGListCompatibility.h file, and imported it in the files where we need the target check.
- Ordered the project by type

In "IGListKit.h" we still have the conditional check for `#if TARGET_OS_EMBEDDED || TARGET_OS_SIMULATOR` - Did we want to make a macro or something for this check?

This is the most Obj-C I've ever done... just felt that was a worthy comment.
