+// Calcul de cumul
+// Tres simple, on note les entites demandees, et a la fin
+// on a le cumul lui-meme, et comme infos derivees, les doubles et les oublis
+// Chaque recouvrement correspond a une augmentation de UN du status
+// Les status demarrent a 2, ainsi a l ajout d une entite, on distingue bien
+// entre les entites nouvelles, liees a cet appel (statut temporaire 1) et les
+// autres (statut superieur ou egal a 2)
