Essential surjectivity of the functor induced on composable arrows

Assuming that L : C ⥤ D is a localization functor for a class of morphisms W that has a calculus of left or right fractions, we show in this file that the functor L.mapComposableArrows n : ComposableArrows C n ⥤ ComposableArrows D n is essentially surjective for any n : ℕ.
