/*! @brief Classe Neumann_homogene Cette classe est la classe de base de la hierarchie des conditions aux limites de type Neumann homogenes.
 *
 *     Une condition aux limites de type Neumann_homogene impose une valeur nulle de la derivee d'un champ inconnue sur une frontiere, ce qui correspond a:
 *
 *       - flux nul impose pour l'equation de transport d'un scalaire
 *       - contrainte nulle imposee pour l'equation de quantite de mouvement
