From: Mike Bayer <mike_mp@zzzcomputing.com>
Date: Wed, 10 Oct 2012 20:12:25 -0400
Subject: - create new sqlalchemy.testing.suite.test_types, starting with
 Unicode round trip tests. - clean out existing test_types:UnicodeTest to be
 strictly individual unit tests against Unicode(), String(), etc. with no
 database access.
