      Parameters:
      perfList - a list of arrays where heurPerfList[t] is the array representing the heuristic performance computed by thread t and perfList[t][h] is the heuristic performance for heuristic 'h' computed by thread 't'
      Returns:
      an array of the average performance for all heuristics where the value at index idx is the average performance of the heuristic at index idx in the universal set.
