* nero/src/MNet.cpp,
nero/src/MDefs.h,
nero/src/RMBK.cpp :
- Ajout d'une prise en compte limitee du pre-routage. Ceci implique de
pouvoir fusionner deux CTerm au cours de la construction d'un CNet.
D'ou l'introduction d'une nouvelle exception "merge_term" qui est
relachee par "CNet::newaccess()" pour etre attrapee par
"CNet::newaccess()".
