Typically intead of doing
minato_isop isop(rel & letter);
while (bdd cube = isop.next()) {
bdd res = bdd_exists(cube, ap)
...
}
do
minato_isop isop(bdd_relprod(rel, letter, ap);
while (bdd res = isop.next()) {
...
}
this way the existential quantification is done once at the same time
of the conjunction, and isop has fewer variable to work with.

When n is an int, doing "new formula[n];" gives us "warning: argument 1
