HEllooooooooo !!!
Gurobi actually crashed Sage when
MixedIntegerLinearProgram(solver="Gurobi") is run with no license
installed (or an invalid one). This if fixed by a if var == NULL before
free(var).
I also noticed that the doctests were actually *all wrong* because of a
solver="GUROBI" instead of solver="Gurobi".
There was also a broken doctest in digraph.py.
After this patch everything is uniform, and all tests pass in the graph/
files with gubori as the default solver.
