Mapping properties of monoid localizations

Given an S-localization map f : M →* N, we can define Submonoid.LocalizationMap.lift, the homomorphism from N induced by a homomorphism from M which maps elements of S to invertible elements of the codomain. Similarly, given commutative monoids P, Q, a submonoid T of P and a localization map for T from P to Q, then a homomorphism g : M →* P such that g(S) ⊆ T induces a homomorphism of localizations, LocalizationMap.map, from N to Q.
