Endofunctors as a monoidal category.

We give the monoidal category structure on C ⥤ C, and show that when C itself is monoidal, it embeds via a monoidal functor into C ⥤ C.

TODO

Can we use this to show coherence results, e.g. a cheap proof that λ_ (𝟙_ C) = ρ_ (𝟙_ C)? I suspect this is harder than is usually made out.

def CategoryTheory.endofunctorMonoidalCategory (C : Type u) [CategoryTheory.Category.{v, u} C] : CategoryTheory.MonoidalCategory (CategoryTheory.Functor C C)

The category of endofunctors of any category is a monoidal category, with tensor product given by composition of functors (and horizontal composition of natural transformations).
