With this update, qdoc is now ready for testing
with multiple trees. In making this change to using
multiple trees, it has become clear that qdoc does
not really need trees the way it currently uses them.
Each C++ class or namespace, or QML type is naturally
a tree tree structure, but above that level, what we
currently call a tree in qdoc should really be called
a collection of maps. This change has moved qdoc in
that direction. It remains to replace the Tree class
with a class that encapsulates a set of maps, one for
each major node type. That can be implemented later.
