A decorator to automatically detect mismatch when overriding a method. See http://stackoverflow.com/questions/1167617/in-python-how-do-i-indicate-im-overriding-a-method
All checks are done when a class or a method is created and not when a method is executed or an instance of a class is created. This means that performace implications are minimal.
