//! ResultFromModel is used to store a final result stored in a
//! TransientProcess, respectfully to its structuration in scopes
//! by using a set of ResultFromTransient
//! Hence, it can be regarded as a passive equivalent of the
//! stored data in the TransientProcess, while an Iterator gives
//! a flat view of it.
//!
//! A ResultFromModel is intended to be attached to the transfer
//! of one entity (typically root entity but it is not mandatory)
//!
//! It is then possible to :
//! - Create and fill a ResultFromModel from a TransientProcess,
//! by designating a starting entity
//! - Fill back the TransientProcess from a ResultFromModel, as it
//! were filled by the operation which filled it the first time
