/*! @brief class Champ_front_var_instationnaire Derived class from Champ_front_var that represents fields on
 *
 *      boundaries variable in space and in time.
 *      Champ_front_var_instationnaire fields are classified depending on whether
 *      their values depend or not on parameters external to
 *      the equation, as Champ_front_var_instationnaire_indep and
 *      Champ_front_var_instationnaire_dep.
 *      The implementation of the field computation must be done in the
 *      mettre_a_jour method.
 *      In the first case (indep), the initialiser method may
 *      call the mettre_a_jour method, but not in the second case
 *      (dep). In either case, it can use the unknown passed
 *      as a parameter as a first estimate.
