Sable/soot — pull request #164 by malaverdiere (2013-12-31 20:37:44+00:00)
Title: Improved Hierarchy

* Modernized implementation to use generics and for-each loop
* Loosened return types from List to Collection
* Added tests that use the old Hierarchy as an oracle for correctness and handles regressions
* Fix for #136

Note: I did not implement the unimplemented methods - is there really a need for it.
