/*! @brief Classe Neumann_homogene This class is the base class of the hierarchy of homogeneous Neumann-type boundary conditions.
 *
 *     A Neumann_homogene boundary condition imposes a zero value of the derivative of an unknown field at a boundary, which corresponds to:
 *
 *       - imposed zero flux for the scalar transport equation
 *       - imposed zero stress for the momentum equation
