changement de version 

changement de strategie pour la génération des NWELL, PWELL, NIMP, PIMP

 1) dans le fichier technoi (.rds) on ne genere du RDS_NWELL qu'a partir
    du NWELL dessiné explicitement par l'utilisateur

 2) S2R genere le PWELL = (ABOX + 0.5*RD_NIMP) - NWELL
    autrement dit on grossit l'AB de 0.5 fois la distance min entre 2 NINP
    et on retire ce qui intersecte de NWELL

    La raison pour laquelle on fait grossir l'AB est que si on place un
    body tie a une demi regle de dessin du bord de l'AB, alors en reel,
    la distance qui separe la zone d'implant du tie du bord de l'AB est
    inférieure a la largeur min de l'implant de la diff, et c'est pour ca
    que l'on fait grossir l'AB.

 3) S2R regenere le NWELL = (ABOX + 0.5*RD_PIMP) - PWELL

 4) S2R regenere le NIMP = PWELL - PTIE

 5) S2R regenere le PIMP = NWELL - NTIE
