// AliFemtoCutMonitorHandler: a handler for cut monitors                 //
// You add cut monitors to the collection which are stored in two        //
// separate collections - one which stores characteristics of the        //
// entities (tracks, particles, pairs, events) that pass the respective  //
// cuts and the other for the ones that fail the cut.                    //
