//! This class allows a general X-STEP engine to run generic
//! functions on any interface norm, in the same way. It includes
//! the transfer operations. I.e. it gathers the already available
//! general modules, the engine has just to know it
//!
//! The important point is that a given X-STEP Controller is
//! attached to a given couple made of an Interface Norm (such as
//! IGES-5.1) and an application data model (CasCade Shapes for
//! instance).
//!
//! Finally, Controller can be gathered in a general dictionary then
//! retrieved later by a general call (method Recorded)
//!
//! It does not manage the produced data, but the Actors make the
//! link between the norm and the application
