    """Add a test case via a class decorator.
    nose uses generators for this but doesn\t work with unittest.TestCase
    subclasses.  So we have to write our own.
    The first argument to this decorator is a test function.  All subsequent
    arguments are the arguments to create each generated test function with in
    the following format:
    Each set of arguments is a two-tuple.  The first element is an iterable of
    positional arguments.  the second is a dict representing the kwargs.
