Note another point of improvement
Quiet the BFS code
Change variables to match domain (capacity), add flow to node
Store capacities with BFS
Make the advanced test data more interesting
Nodes in the path return capacities now
Fix naming collision
Skip paths with no capacity

Also, removed dead code
Spice up the advanced test list
Remove dead code
Alternate path to node 12

7 to 12 has a capacity of 7 and will be used up on the first pass, 10
to 12 should have capacity for the second pass
Ford-Fulkerson is working

(but BFS cannot handle the second pass)
Improve the Ford-Fulkerson test
Add additional debugging
Going to need debug on in the BFS code

It is seg faulting on the residual graph, residual graph looks clean
