I am trying to get a hierarchical tree built using the forest package where each node is labelled with the parent nodes label + the node index, e.g,:
I've tried a lot of different things, including various node walks.There are two issues:1) labels appear directly above nodes (e.g., right on the edge line)2) I can't get this recursive labelling working at all - the best I can do is make each nodes label "parentIndex.nodeIndex"
