 * $Log: doEStructEmpty.C,v $
 * Revision 1.2  2007/05/27 22:46:27  msd
 * Macros for new cut bin modes and centralityData.
 *
 * Revision 1.8  2006/04/04 22:15:56  porter
 * a large number of changes were done to simplify the doEStruct macros
 * in the sense that these are now more similar and should be easier
 * for Duncan's GUI to build.  Here are some examples.
 *
 * Revision 1.7  2005/03/03 01:33:36  porter
 * modified macros
 *
 * Revision 1.6  2004/08/23 19:12:46  msd
 * Added note about usage for pre-compiled cut database
 *
 * Revision 1.5  2004/06/26 16:28:42  porter
 * fixed typo in getDirNames.C
 *
 * Revision 1.4  2004/06/25 03:14:55  porter
 * modified basic macro to take only 1 cutfile and moved some common
 * features into a new macro=support.C.....   this cleaned up the
 * doEStruct macro somewhat
 *
 * Revision 1.3  2004/04/15 18:46:31  msd
 * Updated centrality variable types
 *
 * Revision 1.2  2003/11/21 06:26:40  porter
 * macros for running pythia
 *
 * Revision 1.1  2003/10/15 18:20:57  porter
 * initial check in of Estruct Analysis maker codes.
