 //! A TransferDispatch is aimed to dispatch Entities between two
 //! Interface Models, by default by copying them, as CopyTool, but
 //! with more capabilities of adapting : Copy is redefined to
 //! firstly pass the hand to a TransferProcess. If this gives no
 //! result, standard Copy is called.
 //!
 //! This allow, for instance, to modify the copied Entity (such as
 //! changing a Name for a VDA Entity), or to do a deeper work
 //! (such as Substituting a kind of Entity to another one).
 //!
 //! For these reasons, TransferDispatch is basically a CopyTool,
 //! but uses a more sophiscated control, which is TransferProcess,
 //! and its method Copy is redefined
