CategoryTheory.HasSheafify

HasSheafify means that the inclusion functor from sheaves to presheaves admits a left exact left adjoint (sheafification). Given a functor, preserving finite limits, F : (Cᵒᵖ ⥤ A) ⥤ Sheaf J A and an adjunction adj : F ⊣ sheafToPresheaf J A, use HasSheafify.mk' to construct a HasSheafify instance.
