// Revision 1.7  1998/08/20 14:11:52  hagel
// Add Copy method
//
// Revision 1.6  1998/08/17 16:36:40  hagel
// Make BrDataObject inherit from TObject instead of TNamed
// Include fName and fTitle data members
// Include SetName, GetName, SetTitle, GetTitle methods
// All this done because TTree seems to have problems with TString that is
// used for fName and fTitle in TNamed.
//
// Revision 1.5  1998/08/14 21:26:24  videbaek
// Some cleanup mods
//
// Revision 1.4  1998/08/13 22:20:46  hagel
// Eliminate fCreationID for the moment

// BrDataObject is the base class for all BRAHMS classes             //
// containing data, either as raw data from the DAQ or               //

// The main purpose of the BrDataObject class is to provide          //
// a uniform interface for bookkeeping, information exchange         //

// The individual data objects referring to one event are            //
