29-oct-2003 NvE Obsolete include of AliCalorimeter.h removed from AliEvent header file.
11-nov-2003 NvE Double_t dum=GetScalar() replaced by e[0]=GetScalar() in Ali4Vector.cxx to prevent
                a warning for the gcc compiler (thanks to Thomas Burgess).
                AliJet derived from TNamed instead of TObject to allow identification via name.
12-nov-2003 NvE fDaytime datamember of AliEvent changed from TDatime to TTimeStamp in order to
                obtain nanosecond precision. Setting of date and time via a TDatime argument is
                still supported to provide backward compatibility.
13-nov-2003 NvE Invokation of AliAttrib memberfunction Data() replaced by List() in the example
                in AliAttrib.cxx (was just a typo; thanks Adam Bouchta).
                Also test on pointer value introduced in AliAttrib::GetSlotIndex to prevent
                crash when first slot is empty (thanks to Adam Bouchta).
21-nov-2003 NvE Variable names of type "const" started with the character "k" in various
                memberfunctions of AliMath in order to comply with the strict Alice
                coding conventions.
