package BinMDF
---Purpose: This package provides classes and methods to
-- translate a transient DF into a persistent one and
-- vice versa.
--
-- Driver
--
-- A driver is a tool used to translate a transient
-- attribute into a persistent one and vice versa.
--
-- Driver Table
--
-- A driver table is an object building links between
-- object types and object drivers. In the
-- translation process, a driver table is asked to
-- give a translation driver for each current object
-- to be translated.
