+"""
+ When imported this module adds to CORBA objref from GenericObj type
+ automatic management of reference count
+ The reference count is incremented when the local proxy is created (assignment of __omni_obj attribute)
+ and is decremented when the local proxy is deleted (call of __del__) 
+
+ The GenericObj class for proxy is modified by adding two methods : __del__ and __setattr__
+ The module must be imported before any other import of SALOME CORBA module
