// $Log: BrBbCalHits.h,v $
// Revision 1.2  2002/05/14 18:51:35  cholm
// In the current ROOT CVS head (May 14, 2002) the 'ClassDef' macro has
// changed a lot, meaning that it's no longer nessecary to redefine it
// for nested classes.  Hence, I introduced the header file
// BrNestedHack, which only defined ClassDefNested to something else than
// ClassDef if the version number of ROOT is less than 3.03/05, and then only
// if it's not processed by rootcint.  note, that this meant that preprocessing
// had to be turned on for these (and other) header (rootcint option -p).
// The data classs header files have been changed to include the new
// header file BrNestedHack.h (which is ofcourse installed).
//
// Revision 1.1  2001/09/23 01:38:56  videbaek
// Add class BrBbCalhits very much equivalent to the BrBbRdonew by DO.
// The difference is that the geometry for Bb which is trivial has been removed.
