// Initial revision of brat2
//
// Revision 1.7  2000/12/19 21:46:56  hagel
// Implemented SetEventHeader(BrEventHeader header) method
//
// Revision 1.6  2000/06/15 14:16:47  alv
// Made more of the Get-methods const member functions
//
// Revision 1.5  1999/07/18 21:25:06  videbaek
// Added code to deal with trigger words. This applies to raw data, as well as the
// EventHeader.
//
// Revision 1.4  1999/06/15 23:55:07  hagel
// Added fEventType in BrEventHeader since it is in raw data
//
// Revision 1.3  1999/01/21 23:23:19  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
