This PR adds a new local search operator: FP with objective cutoff. We were using FP as a means of solution generation algorithm. Now we are also using it as a local search by adding a cutting plane at the current fesible point perpendicular to the objective. We rerun FJ at this point to have a different restart point and continue the FP search with the cutting plane added. This on brings down the average optimality gap by 1-2%.
