in AliTimestamp.
25-mar-2007 NvE AliTimestamp extended with Apparent Sidereal Time.
+27-mar-2007 NvE Test on date/time validity corrected in AliTimestamp::SetMJD to prevent
+ crash in TTimestamp invokation for very future dates.
+ Also more accurate calculation introduced of the change (dpsi) in
+ ecliptic longitude due to nutation in AliTimestamp::GetGAST.
+28-mar-2007 NvE AliTimestamp::Date extended to provide apparent sidereal time via
+ specification of negative "mode" parameter.
+29-mar-2007 NvE New memberfunction Almanac() introduced in AliTimestamp to provide a
+ central place for calculation of astronomical observables.
+31-may-2007 NvE Memberfunctions GetNdevices, GetIdDevice and ShowDevices of AliEvent
+ extended to select device classes.
+23-jun-2007 NvE Support for locking introduced in AliAttrib and locked signal (and error)
+ treatment implemented in SetSignal() and SetSignalError() of AliSignal.
+ Also the AliSignal copy constructor has been updated for the new locking.
+08-sep-2007 NvE New memberfunctions SetEpoch and GetEpoch introduced in AliTimestamp
+ for convenience.
+13-sep-2007 NvE New class AliAstrolab introduced to relate (local) measurements with
+ astrophysical phenomena.
+13-sep-2007 NvE Hour angle info included in printout of AliAstrolab.
+26-sep-2007 NvE AliTrack extended with GetNsignals for a specific signal class.
+ Also AliJet extended with GetNtracks for a specified track name.
+27-sep-2007 NvE New memberfunction RemoveDevice() introduced in AliEvent.
+ AliAstrolab derived from TTask, to provide a base class for TTask
+ based processors.
+ New class AliEventSelector introduced.
+03-oct-2007 NvE Class AliMath extended with statistical analysis facilities
+ PsiValue and Chi2Value to investigate statistical significance
+ of observations in counting experiments.
+06-oct-2007 NvE Memberfunctions Chi2Value of class AliMath extended with ndf determination.
+09-oct-2007 NvE Memberfunctions ResetSignals and DeleteSignals of class AliSignal
+ extended with options to preserve the waveform histo contents.
+ These new options are now also used in the SetSignal and SetSignalError
+ memberfunctions of class AliSignal.
+15-oct-2007 NvE Typo corrected in docs of AliAstrolab.cxx and memberfunctions GetMedian
+ and GetSpread of AliSample.cxx extended for Y-values of histo data.
+09-nov-2007 NvE Graphical skymap facilities introduced in AliAstrolab, based on the
+ work by Garmt de Vries-Uiterweerd.
+09-nov-2007 GdV Automatic central meridian setting only activated when meridian
+ has a value smaller than -pi. This will allow also negative values
+ as user input.
+14-nov-2007 NvE Copy constructor and Clone() memberfunction introduced in AliObjMatrix.
