The total complex of a bicomplex

Given a preadditive category C, two complex shapes c₁ : ComplexShape I₁, c₂ : ComplexShape I₂, a bicomplex K : HomologicalComplex₂ C c₁ c₂, and a third complex shape c₁₂ : ComplexShape I₁₂ equipped with [TotalComplexShape c₁ c₂ c₁₂], we construct the total complex K.total c₁₂ : HomologicalComplex C c₁₂.

In particular, if c := ComplexShape.up ℤ and K : HomologicalComplex₂ c c, then for any n : ℤ, (K.total c).X n identifies to the coproduct of the (K.X p).X q such that p + q = n, and the differential on (K.total c).X n is induced by the sum of horizontal differentials (K.X p).X q ⟶ (K.X (p + 1)).X q and (-1) ^ p times the vertical differentials (K.X p).X q ⟶ (K.X p).X (q + 1).

Lemmas in the totalAux namespace should be used only in the internals of the construction of the total complex HomologicalComplex₂.total. Once that definition is done, similar lemmas shall be restated, but with terms like K.toGradedObject.ιMapObj replaced by K.ιTotal. This is done in order to prevent API leakage from definitions involving graded objects.
