+// Gets all the art tags which are ancestors of this one as a "baobab tree" -
+// what you'd typically think of as roots are all up in the air! Since this
+// really is backwards from the way that the art tag tree is written in data,
+// chances are pretty good that there will be many of the exact same "leaf"
+// nodes - art tags which don't themselves have any ancestors. In the actual
+// data structure, each node is a Map, with keys for each ancestor and values
+// for each ancestor's own baobab (thus a branching structure, just like normal
+// trees in this regard).
