Returning list of paths in Edmond Karp's

[Azzaare]

I need to extract the set of paths composing the max-flow returned by Edmond Karp's algorithm (or any augmenting paths method). Do you mind if I add this set of paths to the edmonds_karp_impl function as a returned value?

If it is OK, I will make a push request soon.

Can this be derived from the flow_matrix? If so, it might be better as a standalone function.

[Azzaare]

You're correct, I was probably being lazy. Then I will write down some flow_decomposition function for any flow matrix and make a PR.
