This diff resolves all known consistency issues with ASTableView and ASCollectionView. It includes significantly more aggressive thrash-testing in ASTableViewStressTest, which now passes on a variety of device and simulator configurations. It also updates the unit tests run on every commit to ensure any regression is caught quickly. A few of the salient changes in this diff: - ASTableView now uses Rene's ASCollectionViewLayoutController, and actually uses a UICollectionViewFlowLayout without any UICollectionView. This resolves an issue where ASFlowLayoutController was generating slightly out-of-bounds indicies when programmatically scrolling past the end of the table content. Because the custom implementation is likely faster, I will revisit this later with profiling and possibly returning to the custom impl. - There is now a second copy of the _nodes array maintained by ASDataController. It shares the same node instances, but this does add some overhead to manipulating the arrays. I've filed a task to follow up with optimization, as there are several great opportunities to make it faster. However, I don't believe the overhead is a significant issue, and it does guarantee correctness in even the toughest app usage scenarios. - ASDataController no longer supports calling its delegate /before/ edit operations. No other class was relying on this behavior, and it would be unusual for an app developer to use ASDataController directly. However, it is possible that someone with a custom view that integrates with ASDataController and ASRangeController could be affected by this. - Further cleanup of organization, naming, additional comments, reduced code length wherever possible. Overall, significantly more accessible to a new reader.
