/*! @brief Sortie_libre_Gradient_Pression_impose
 *
 *  Cette classe derive de la classe Neumann_sortie_libre
 *
 *     Elle represente une frontiere ouverte avec condition de gradient de pression impose.
 *     L'objet de type OWN_PTR(Champ_front_base) le_champ_front contient le gradient impose. La fonction flux_impose() renvoie une valeur de pression
 *     a l'exterieur calculee a partir du gradient de pression impose et de la pression a l'interieur du domaine.
