Extract OLEContainerScrollViewContentView into separate file
Add multiple table views scene to demo app
Animate layout during collection/table view cell updates

Using method swizzling to hook into animated cell updates of UICollectionView and UITableView.

- The implementation for UICollectionView is based on public API ([UICollectionViewLayout finalizeCollectionViewUpdates] and should not cause any problems.

- The implementation for UITableView swizzles a private method ([UITableView _endCellAnimationsWithContext:]. The swizzled method also has to create its own animation block to update the container view's contentSize because there is no delegate method to run an animation inside the table view's animation block.
