LNS documentation is wrong

[Dimosts]

Hello,

in the documentation for using LNS- (https://choco-solver.readthedocs.io/en/latest/3_solving.html and https://choco-solver.org/docs/solving/lns/), the following code is given to run lns in tandem with CP:

solver.setLNS(INeighborFactory.random(ivars, new FailCounter(solver, 100));
solver.findOptimalSolution(Model.MINIMIZE, objective);

However, they have some flaws:

1. A parenthesis is missing in the first line
2. The arguments should be 1st the objective variable and 2ond the direction

I got them to work with:

solver.setLNS(INeighborFactory.random(F), new FailCounter(solver, 100));
solver.findOptimalSolution(objective, Model.MINIMIZE);
