// ConeJetInfo.hpp
// Purpose: Hold informations about the cone jets that do not fit into
//   a CalTClusterChunk/IntEclusterChunk.
//
// Created: Laurent Duflot 31-JUL-2000
//
// Modified:
//  09-Aug-2000 Laurent Duflot
//   + add initial jet ET (i.e. before split/merge) 
//    1-May-2007 Lars Sonnenschein
//    extracted from D0 software framework and modified to remove subsequent dependencies

// History of Changes in FastJet compared tothe original version of
// ConeJetInfo.hpp
//
// 2011-11-14  Gregory Soyez  <soyez@fastjet.fr>
//
//         * changed the name of a few parameters to avoid a gcc
//           -Wshadow warning
//
// 2009-01-17  Gregory Soyez  <soyez@fastjet.fr>
//
//        * put the code in the fastjet::d0 namespace
