-# A Set class that works all the way back to Python 1.5.  From:
-#
-#       Python Cookbook:  Yet another Set class for Python
-#       http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/106469
-#       Goncalo Rodriques
-#
-#       This is a pure Pythonic implementation of a set class.  The syntax
-#       and methods implemented are, for the most part, borrowed from
-#       PEP 218 by Greg Wilson.
-#
-# Note that this class violates the formal definition of a set() by adding
-# a __getitem__() method so we can iterate over a set's elements under
-# Python 1.5 and 2.1, which don't support __iter__() and iterator types.
