Compatibilities of properties of morphisms with respect to composition

Given P : MorphismProperty C, we define the predicate P.IsStableUnderComposition which means that P f → P g → P (f ≫ g). We also introduce the type classes W.ContainsIdentities, W.IsMultiplicative, and W.HasTwoOutOfThreeProperty.
