Subject: [PATCH] Relax type of TestCase.assertCountEqual() params from
 Sequence to Iterable (#1006)

The stubs for `unittest.TestCase.assertCountEqual()` specify the parameters are Sequences; in fact the method works fine with Iterables, as the first thing the method does is convert them to lists.  [1]  The docs do say sequences, but it appears there is no reason they cannot be Iterables.
