Description

Computes the colimit of an arbitrary diagram in Set: - the set is the disjoint union of all sets in the diagram (which we obtain by pairing elements with the node number) factored by the equivalence generated by the pairs (x, f_i(x)), with i an arrow in the diagram - structural morphisms are factorizations
