> Move ml.tree.impl.RandomForest.predictNodeIndex to LearningNode.
> We need to keep it as a separate method from Node.predictImpl because (a) it needs to operate on binned features and (b) it needs to return the node ID, not the node (because it can return the ID for nodes which do not yet exist).
