Given a TotalComplexShape c₁ c₂ c, a functor F : C₁ ⥤ C₂ ⥤ D, we study the behavior with respect to homotopies or the functoriality of the action of F on homological complexes: if f₁ and f₁' are homotopic maps, then the maps mapBifunctorMap f₁ f₂ F c and mapBifunctorMap f₁' f₂ F c are also homotopic.


Hopefully, it might be possible to deduce the symmetric property for the second variable from this result on the first variable and a study of the flip of functors...

…lexes factors through homotopies (#10800)

Given a `TotalComplexShape c₁ c₂ c`, a functor `F : C₁ ⥤ C₂ ⥤ D`, we study the behavior with respect to homotopies or the  functoriality of the action of `F` on homological complexes: if `f₁` and `f₁'` are homotopic maps, then the maps `mapBifunctorMap f₁ f₂ F c` and `mapBifunctorMap f₁' f₂ F c` are also homotopic.
