* [ASCellNode] Added indexPath property.
* [ASCellNode] Cached the type of scrollView we're using in the node, and placed that logic in setScrollView.
* [ASCellNode] Removed table and collection view from indexPath, since they return the index paths from the view-space.
* Changed the logic for getting indexPath so that it works even when the cell is not displayed.
* [VerticalWithinHorizontalScrolling] Explicitally synthesized indexPath property.
* Separate dataSource & UIKit index spaces

Do not call layout delegate method before the cell node is loaded. This can happen if
application code calls -setNeedsLayout on the cell manually, and can confuse UIKit state
because we submit an empty batch update call on the next runloop.
