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
- [x] Test moving without batch
