Create an Iterator type with classes ForwardIterator and ReverseIterator, having GetFirstChild/GetNextSibling and GetLastChild/GetPrevSibling methods, respectively. Specify the iterator type for each call to ForEachNode. With this, we can support trees with forward and reverse sibling structures. Additionally, apply these algorithms to all Layer recursive traversals, where applicable. Update tests to ensure both directions yield expected results.
