  On input
  doAction - 0 just fix in original and return NULL

             2 as one but use presolve Inside this
             3 use presolve and fix ones with large cost
             ? do heuristics and set best solution
             ? do BAB and just set best solution
             10+ then use lastSolution and relax a few
             -2 cleanup afterwards if using 2
  On output - number fixed
