Comment:

 And here are the modifications to CPLEX and Coin. The doctests pass, plus
 all the methods of Graph/Digraph/GenericGraph pass with both GLPK, Coin
 and CPLEX.

 I agreed with you patch almost everywhere ! The only modification I made
 is the "constraints" argument you had placed in the add_constraint method.
 I really didn't get why you picked this name. I made it "coefficients", as
 the pairs are actually the coefficient of the sparse matrix, but of course
 we can discuss it during the review `:-)`
