// This class which defines defines the Trigger Configuration 
//
// Trigger Configuration defines the trigger setup for a particular run
// We have default configurations for each running mode (Pb-Pb, p-p, p-A, Calibration, etc).
// It keep:
//   All the information conained in the CTP configuration file used
//   online during the data taking
//
// Configurations could be created and stored in local file.
// By default the configuration is loaded from the corresponding GRP entry
// inside the OCDB. There one can have one and only one configuration per run.
//
//   Example how to create a Trigger Configuration:
//
//   AliTriggerConfiguration config( "TEST", "Test Configuration" );
//
//   // Define a Cluster Detector
//   config.AddDetectorCluster( "VZERO ZDC MUON" );
//
//   // Define the trigger conditions (see AliTriggerCondition.cxx)
//   config.AddCondition( "VZERO_TEST1_L0 & MUON_SPlus_LPt_L0 & ZDC_TEST2_L0", // condition
//                         "VO1_M1_ZDC2",      // short name
//                         "Dummy",            // short description
//                          0x0100 );          // class mask (set one bit)
//
//   config.AddCondition( "VZERO_TEST2_L0 & MUON_SMinus_HPt_L0 & ZDC_TEST1_L0",
//                         "VO2_M3_ZDC1",
//                         "Dummy",
//                          0x0200 );
//
//   config.AddCondition( "VZERO_TEST3_L0 | MUON_Unlike_LPt_L0 | ZDC_TEST3_L0",
//                         "VO3_M1_ZDC3",
//                         "Dummy",
//                          0x0400 );
//   config.CheckInputsConditions("Config.C");
//   config.Print();
//
//   // save the configuration to file
