// $Log: BrDataObject.h,v $
// Revision 1.1.1.1  2001/06/21 14:54:58  hagel
// Initial revision of brat2
//
// Revision 1.13  2001/06/01 15:46:10  cholm
// Fixed creation id class to be more clean.  Now sets the user name
// (if avaliable) has a Print method.
// PRint method in BrDataObject.
// Print method in BrDataTable
// Print method in BrEvent
// Print method in BrEventNode
//
// Revision 1.12  2001/01/29 19:58:46  cholm
// Added konstant kInvalidValue for general use
//
// Revision 1.11  2000/11/15 16:08:06  videbaek
//  file cleanup
//
// Revision 1.10  2000/06/03 18:17:02  videbaek
// Changed inheritance of BrIOModule. Added utility to BrDataObject.. See Update message for more info
//
// Revision 1.9  2000/04/13 00:01:55  cholm
// Added methods for browsing BrEvents, either directly or via
// a BrEventIO. Also added method GetROOTFile to BrEventIO.
//
// Revision 1.8  1999/05/12 16:22:20  hagel
// Implemented + , =+ and = operators for BrEventNode.  These will be useful
// for adding events together.  Has been tested for single pion events and seems
// to work. In the course of implementing this, several conflicts with const were
// identified.  These were cleaned up by adding appropriate const's where needed.
// It was checked that it did not break other things.
//
// Revision 1.7  1999/01/21 23:23:18  hagel
// 1. Changed convention for checking includes.  Current convention is:
//    BRAT_Br...... eg BRAT_BrModule ala ROOT.
// 2. Added CVS logs to .h files that didn't have them.
// 3. Moved checking of include definition to first line for easier reading
// 4. Put checks before all includes in the include files as per BRAT specifications
// 5. Added BrGeantHeader to Geant Makefile
// 6. All changes have been checked to compile on NT ala Cygnus
//
// Revision 1.6  1998/08/20 14:00:33  hagel
// Add Copy method
//
// Revision 1.5  1998/08/17 16:38:12  hagel
// Make BrDataObject inherit from TObject for the purpose of using in Trees
// Include fName, fTitle data members
// Include SetName, GetName, SetTitle, GetTitle methods
// All this because TTree seems to have problem working with TString.
//
// Revision 1.4  1998/08/14 21:26:23  videbaek
// Some cleanup mods
//
// Revision 1.3  1998/08/13 22:20:56  hagel
// Eliminate fCreationID for the moment
//
// Revision 1.2  1998/03/09 20:53:32  videbaek
// Ensure that pointers are non-NULL before deleting
//
//
