Fin du phasage de la dynamique parallele localisee (petite memoire) avec le tronc LMDZ5 r1671
Il reste quelques routines a verifier (en particulier ce qui touche a l'etude des cas academiques)
et la validation a effectuer

End of the phasing of the localised (low memory) parallel dynamics package with the
LMDZ5 trunk (r1671)
Some routines still need some checking (in particular the academic cases) and some
validation is still required
