40 * Revision 1.2 2003/10/11 14:46:00 e_gourgoulhon
41 * Line 65-67: changed the name of local variable "triad" to "triad0"
42 * in order not to shadow the class member triad.
43 *
44 * Revision 1.1 2003/09/25 08:56:28 e_gourgoulhon
45 * First version (uses Cmp and Tenseur as intermediate quantities).
