2006-11-07 haftmann 2006-11-07 made locale partial_order compatible with axclass order
2006-11-07 krauss 2006-11-07 * Added annihilation axioms ("x * 0 = 0") to axclass semiring_0. Richer structures do not inherit from semiring_0 anymore, because anihilation is a theorem there, not an axiom. * Generalized axclass "recpower" to arbitrary monoid, not just commutative semirings.
