/*! @brief classe Dirichlet Cette classe est la classe de base de la hierarchie des conditions aux limites de type Dirichlet.

 *     Une condition aux limites de type Dirichlet impose la valeur d'un champ inconnue sur une frontiere, ce qui correspond a:
 *
 *      - vitesse imposee pour l'equation de Navier-Stokes
 *      - scalaire impose pour l'equation de transport d'un scalaire
