//     OADB interface for the physics selection
//     Author: Michele Floris, CERN
//    
// This class contains the parameters needed to configure the physics
// selection. The online trigger class must be associated to an
// offline trigger mask, as defined in
// AliVEvent::EOfflineTriggerTypes.  The offline condition, even for
// the same trigger mask, can be different for every different online
// trigger, so it must be given as a parameter in the Add...Class
// methods.  It's up to the user to set the appropriate offline
// conditions when filling the class.
