* Add unit test to confirm that supplementary items must be contained within actual sections
* [ASLayoutInspecting] Deprecate collectionView:numberOfSectionsForSupplementaryNodeOfKind:
* Add another test to dig deeper into UICollectionView
* Perhaps controversially, decomposing ASRangeControllerUpdateRangeProtocol+Beta.h such that the categories on various classes are defined in the classes themselves since that's where the implementation of those categories is provided.
* Updating unit tests and import other headers the tests took for granted. The tests could probably import the umbrella header and not have to worry about this.
* Updating the "Life without Cocoapods" sample to build and run dependent on ASDK as a static library.
* Added a "Life With Frameworks" sample app to build and run dependent on ASDK as a framework, proving the framework targets work.
