/**
 * Classe permettant de diminuer au maximum l'allocation de tableau de int pour
 * les dimensions. Cette classe n'est pas multithread, il faut créer une
 * instance par thread. Il faut bien réfléchir lorsque l'on souhaite utiliser
 * cette classe, par exemple il ne faut pas l'utiliser dans une méthode qui
 * appelle une autre methode réutilisant le meme objet, car il sera alors
 * modifier alors qu'il ne le faut pas pour la premiere methode appelée.
