An equivalence relation defines a *set* of equivalence classes which partition
the objects the relation operates on. For example, the "same signum value"
equivalence relation on integers has three equivalence classes :
1) negative nonzero numbers (corresponding to signum == -1)
2) zero (corresponding to signum = 0)
3) positive nonzero numbers (corresponding to signum ==1)
