/*! @brief class Sortie_libre_Gradient_Pression_impose
 *
 *   This class derives from Neumann_sortie_libre.
 *   It represents an open boundary with an imposed pressure gradient condition.
 *   The OWN_PTR(Champ_front_base) le_champ_front holds the imposed gradient. The flux_impose() function returns an external pressure
 *   value computed from the imposed pressure gradient and the internal pressure of the domain.
