Walk the pytables group hierarchy for pandas objects.
This generator will yield the group path, subgroups and pandas object
names for each group.
Any non-pandas PyTables objects that are not a group will be ignored.

child groups (following an alphanumerical order) is also traversed,
following the same procedure.
