AddMonCat.FilteredColimits.colimit_zero_eq
∀ {J : Type v} [inst : CategoryTheory.SmallCategory J] (F : CategoryTheory.Functor J AddMonCat)
[inst_1 : CategoryTheory.IsFiltered J] (j : J), 0 = AddMonCat.FilteredColimits.M.mk F ⟨j, 0⟩The definition of the "zero" in the colimit is independent of the chosen object
of J. In particular, this lemma allows us to "unfold" the definition of colimit_zero at
a custom chosen object j.
