/* What this test tests is the ability to add interfaces dynamically; in

 * initialized.

 *

 * The test defines 5 interfaces:

 * 

 * - TestIface1 is added before the class is initialized

 * - TestIface2 is added in base_object_base_init()

 * - TestIface3 is added in test_iface1_base_init()

 * - TestIface4 is added in test_object_class_init()

 * - TestIface5 is added in test_object_test_iface1_init()

 * - TestIface6 is added after the class is initialized
