An empty tagging interface that can be used if a java class want control over the class dict initialization. When a java class implements this interface, it must also have a method like:

      public static void classDictInit(PyObject dict) { .. }

The method will be called when the class is initialized. The method can then make changes to the class's __dict__ instance, f.example be removing method that should not be avaiable in python or by replacing some method with high performance versions.
