01-dec-2001 NvE SetOwner() introduced for certain TObjArray's in AliCalcluster, AliEvent,
                AliInvmass, AliJet, AliTrack and AliVertex to adapt to the new memory
                management of ROOT 3.01 (and later) in case of reading trees.
06-dec-2001 NvE Memory usage optimised for AliVertex & co. and memory leak due to
                cloning solved.
07-dec-2001 NvE ClassDef() and ClassImp() statements introduced for AliSample.
17-dec-2001 NvE Copy constructor and Init() memberfunction introduced for AliTrack & co.
14-jan-2002 NvE New schema evolution activated via the "+" behind the classnames
                in RALICELinkDef.h. Note that the new schema evolution only works
                correctly for ROOT version 3.02/07 and later.
