/*! @brief classe Champ_front_var_instationnaire Classe derivee de Champ_front_var qui represente les champs aux
 *
 *      frontieres variables en espace et dans le temps.
 *      Les Champ_front_var_instationnaire sont classes suivant que
 *      leurs valeurs dependent ou non de parametres externes a
 *      l'equation, en Champ_front_var_instationnaire_indep et
 *      Champ_front_var_instationnaire_dep.
 *      L'implementation du calcul du champ doit se faire dans la
 *      methode mettre_a_jour.
 *      Dans le premier cas (indep), la methode initialiser peut
 *      appeler la methode mettre_a_jour, mais pas dans le second cas
 *      (dep). Elle peut de toutes facons utiliser l'inconnue qui lui
 *      est passee en parametre comme une premiere estimation.
