// This class takes care of simulating the output from the pixel   //
// trigger system.                                                 //
// The fast-or signals are given as input and they are processed   //
// to see which algorithm will give a signal to the central        //
// trigger system. To avoid doing the same operations many times,  //
// there is a method called PreprocessFOSignals, which should      //
// always be called for each event before the processing of        //
// each individual algorithm is done.                              //
//                                                                 //
// As soon as a new algorithm has been implemented online, a       //
// corresponding method should be implemented here. Which method   //
// should be used for a given trigger label is taken care of in    //
// ProcessFOSignalsLabel method.                                   //
//                                                                 //
