//  Class to define a Trigger Input from an specific detector                                                                                           //
//
//
//                        name         description     id mask
//    Ej:
//      AliTriggerInput( "V0_MB_L0", "VO minimum bias", 0x01 );
//      AliTriggerInput( "V0_SC_L0", "VO semi central", 0x02 );
//      AliTriggerInput( "V0_C_L0",  "VO central",      0x04 );

//    The name must be globaly unique. Spaces are not allowed.
//    As convention should start with detector name then an id
//    and the trigger level (L0, L1, L2)
//
//    A maximun of 60 inputs trigger are allow.
//    So, the id mask should set only bit from the position 1 to 60.
