Given a functional this method tries to find a root near an initial guess sol. The two methods that the functional must have are evalRes and solveJac. If solveJac inverts the exact Jacobian of the functional, than this is equivalent to a Newton method. If convergence do not appens in the expected ratio, a NonLinearLineSearch algorithm is called (uadratic or parabolic).
