 * @brief The directive is a Motcle such as "vitesse", "pression",
 *  "temperature", "champ_elem" (creates a P0-type field), etc.
 *  This method determines the type of field to create based on the element type
 *  and the discretisation directive. It then determines the number of DOFs
 *  and sets all field parameters (type, nb_compo, nb_ddl, nb_pas_dt,
 *  name(s), unit(s) and field nature) and associates the Domaine_dis to the field.
 *  See the code for the correspondence between directives and the created field type.
 * @param directive Keyword specifying the type of field to create.
 * @param z Discretised domain.
 * @param nature Nature of the field.
 * @param noms Field name(s).
 * @param unites Field unit(s).
 * @param nb_comp Number of components.
 * @param nb_pas_dt Number of time steps.
 * @param temps Current time.
 * @param champ Output field (instationary).
 * @param sous_type Optional subtype name.
