/*! @brief Class Extruder_en3 This class is an interpreter that serves to read and execute
 *
 *     the Extruder_en3 directive:
 *         Extruder_en3 { nb_domain domain_name1 domain_name2 .. direction nb_slices }
 *     This directive is to be used in VEF 2D discretization to obtain
 *     a 3D mesh by extrusion then cutting.
 *    Here each triangle is extruded into a prism, then cut into 3 tetrahedra.
 *
 * @sa Interprete Extruder_en3, This class is usable in 3D
