There are m+1 (m constraints + 1 obj) components: size of each lamI_.
Implementing a FP requires adding one for gg', the gradient again being set up at the beginning (at least its expression members are known).
This can simply be hacked by the FP itself. Same for the changed hessian, simply replace the CouenneProblem's objective with sum (objective, norm)
Actually, we could do the gg' trick by replacing the objective with sum (objective, norm, gg')
