allow setup to pass info to teardown

[GoogleCodeExporter]

Would be nice to have the ability to have setup pass something to teardown.

When using a class, this is typically done with class attributes:

    class test_stuff:
        def setUp(self):
            self.remember = 'something'
        def tearDown(self):
            if self.remember == 'something': ...

But when using decorators (@with_setup) and such, this isn't available.

This is especially useful when the test run needs a temporary directory to 
run in and setup creates that directory; passing the directory name to 
teardown would be useful.
