Claudio Squarcella updated SANDBOX-385:
---------------------------------------

    Attachment: SANDBOX-385_AddedEdmondsKarpImplementationAndTest.patch

Hello,

I implemented Edmonds-Karp plus a test for it.

I also found a bug in the previous implementation of {{DefaultVisitAlgorithmsSelector}} and
fixed it: vertices are added to the visit stack/queue only if the edge leading to them is
actually discovered.

Finally I extracted common code in the {{FlowNetworkHandler}} creating a utility class called
{{FlowNetwork}}, that represents a directed graph with flow capacity.

Hoping this helps,
Claudio
