Iterate over the cases.
Parameters
----------
source : 'problem', 'driver', component pathname, solver pathname, case_name
Identifies which cases to return.
recurse : bool, optional
If True, will enable iterating over all successors in case hierarchy.
flat : bool, optional
If False and there are child cases, then a nested ordered dictionary
is returned rather than an iterator.
