Homology of the extension of an homological complex

Given an embedding e : c.Embedding c' and K : HomologicalComplex C c, we shall compute the homology of K.extend e. In degrees that are not in the image of e.f, the homology is obviously zero. When e.f j = j, we construct an isomorphism (K.extend e).homology j' ≅ K.homology j.
