| void BlisModel::passInPriorities | ( | const int * | priorities, | |

Pass in branching priorities.
If ifClique then priorities are on cliques otherwise priorities are on integer variables. Other type (if exists set to default) 1 is highest priority. (well actually -INT_MAX is but that's ugly) If hotstart > 0 then branches are created to force the variable to the value given by best solution. This enables a sort of hot start. The node choice should be greatest depth and hotstart should normally be switched off after a solution.
If ifNotSimpleIntegers true then appended to normal integers
