Or to put this section more succinctly: Why should cost be a number?

What operations do the minimum cost flow algorithms demand of this thing called "cost", and can we provide those operations using something which is not a number but is instead a different structure?
What is the minimal interface that the mincostflow algo demands of this "cost" datatype?
