This class constructs and maintains a tree of instances of

though the pointer to the singleton QDocDatabase.
Tree is being converted to a forest. A static member provides a
map of Tree* values with the module names as the keys. There is
one Tree in the map for each index file read, and there is one
tree that is not in the map for the module whose documentation
is being generated.

One map is indexed by ref, the other by title. The ref
