ASCellNode doesn't have a supernode reference

ASCellNode doesn't have a reference to the supernode (ASTableNode or ASCollectionNode)

Apparently the reason is in this lines. Because not all UIView have a corresponding asyncdisplaykit_node.

Especially in the case of ASTableNode and ASCollectionNode, there are intermediate views between ASCollectionView/ASTableView and ASCellNode-View
