Add dictionary export to PathTree

PathTree is a dictionary extension with paths as keys and lets
you do things like iterate on subpaths, etc.  Internally it is
implemented as a nested dictionary but on the outside it acts
like a normal dictionary.

This change enables exporting a PathTree structure as a nested
dictionary, which is useful for python_2_xyz encoders that understand
nested data structures.
