Univ.constraints made fully abstract instead of being a Set of abstract stuff
No need to tell the world about the fact that constraints are
implemented via caml's Set. Other modules just need to know about
the empty and union functions (and addition functions "enforce_geq"
and "enforce_eq" that were already there).
