and Ali4Vector respectively. This allows to use this memberfunction also in
all the derived classes (e.g. AliPosition, AliSignal, AliTrack, etc...).
Therefore the Load() memberfunction has been removed from AliPositionObj.
+03-oct-2003 NvE Typos fixed in AliCalorimeter.cxx.
+ Also memberfunction MakeCopy introduced in class AliCalorimeter.
+07-oct-2003 NvE Arguments of SetSignal and AddSignal memberfunctions of AliCalmodule corrected
+ to comply with the corresponding virtual functions of AliSignal.
+ AliCalorimeter modified accordingly.
+09-oct-2003 NvE Argument of all MakeCopy memberfunctions removed to obey the ANSI C++ rules for
+ virtual functions and to prepare for a common base class.
+ Due to the fact that not all compilers seem to accept the standard ANSI rule
+ that a virtual function is allowed to differ in return type from the corresponding
+ virtual function in the base class, the MakeCopy() memberfunctions have all been
+ given a return type of TObject*.
+ Also AliAttrib::Data renamed to AliAttrib::List to prevent violation of ANSI virtual
+ function rules and class AliSignal updated accordingly.
+ Memberfunction ResetPosition() moved from AliSignal to AliPosition.
+ Explicitly declared all memberfunctions virtual in the derived classes in case
+ the corresponding memberfunctions were also declared virtual in the base class.
+ Various memberfunctions which were declared virtual but were actually not meant
+ to be overridden declared as non-virtual in various low-level classes like
+ Ali3Vector, Ali4Vector, AliPosition etc...
+13-oct-2003 NvE Argument 'npt' of AliCollider::MakeEvent also made optional.
+24-oct-2003 NvE Private memberfunction Dump of AliTrack and AliVertex renamed to Dumps in order
+ not to override the Dump memberfunction of TObject.
+ Also definition of AliVertex::Draw slightly modified to comply with the standard
+ ANSI virtual function rules concerning TObject::Draw.
+ Invokation of ClassName() used in printout of AliSignal::Data to make the output
+ information more generic.
+25-oct-2003 NvE Memberfunction AddCalorimeter of AliEvent replaced by memberfunction AddDevice
+ to make the functionality more generic.
+ To comply with the enhanced flexibility of AliEvent::AddDevice the class
+ AliCalorimeter has been derived from TNamed and the MakeCopy() memberfunction
+ has been replaced by Clone() to override the default one of TNamed.
+ The specific GetName and SetName memberfunctions of AliCalorimeter have been removed.
+26-oct-2003 NvE Class AliSignal derived from TNamed and MakeCopy() memberfunction replaced by Clone()
+ like was done for AliCalorimeter.
+ The latter was also done for AliCalmodule and AliAttribObj.
+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.
+22-nov-2003 NvE Support for various computation modes introduced in AliMath::Prob.
+23-nov-2003 NvE New memberfunctions GetBetaVector(), GetBeta() and GetGamma() introduced in Ali4Vector.
+03-dec-2003 NvE Message removed from AliEvent::GetDevice in case there are no devices present.
+05-dec-2003 NvE Memberfunction SetStable introduced in AliCollider for the user's convenience.
+08-dec-2003 NvE AliTrack derived from TNamed to enhance labeling flexibility and also specific
+ Clone memberfunction introduced to enable storage of derived objects in AliJet & co.
+ Also specific Clone memberfunctions introduced for AliJet, AliVertex and AliEvent and
+ for the already existing specific Clone memberfunctions the default argument was set
+ to the empty string "".
+15-dec-2003 NvE Datamembers fNdec and fNsig removed from AliTrack since these data are now retrieved
+ directly from the corresponding arrays.
+ Support for hypothesis probability introduced in AliTrack and old mass hypothesis
+ machinery extended to provide now full track hypotheses.
+18-dec-2003 NvE Support for object references from the various signal slots introduced in AliSignal.
+ Since this is mainly intended for "backward references" to AliTrack objects,
+ the AliTrack class has been slightly updated for this to provide pointer consistency
+ in case the corresponding AliTrack object is deleted.
+19-dec-2003 NvE Slight modification in AliVertex.h and AliAttribObj.cxx to prevent gcc compiler
+ warning concerning an unused variable.
+22-dec-2003 NvE Event selection introduced in AliCollider.
+24-dec-2003 NvE Some cosmetics in printout of AliVertex, AliEvent and AliCollider.
+ Support for spectator tracks introduced in AliCollider.
+28-dec-2003 NvE Facility introduced in AliCollider to set minimal momentum for spectator tracks
+ to be stored.
+06-feb-2004 NvE "char* name" changed to "const char* name" in all specific Clone memberfunctions
+ to prevent compiler warnings on Sun.
+ Memberfunction Set() of TTimeStamp used in AliEvent instead of setting the date/time
+ via the TTimeStamp constructor. This is only possible with ROOT version 3.10/02 or later,
+ since for earlier versions the TTimeStamp::Set memberfunctions were erroneously declared
+ private.
+11-feb-2004 NvE In script "gcclib" the option -Wno-long-long added to prevent warnings from the usage
+ of type "long long" in Rtypes.h
+12-feb-2004 NvE In AliCollider::MakeEvent the statement "char* name" was replaced by "char name[16]" to
+ comply with TPythia6 convention. Also the hardcoded values of the p and n masses have
+ been replaced by masses obtained from the Pythia system via a call to GetPMAS().
+ Because of a bug in TPythia6 the function Pymass() couldn't be used directly.
+13-feb-2004 NvE AliCollider::GetPyname introduced to provide a correctly stripped character string
+ for the particle names. The name returned by TPythia6::Pyname contains trailing
+ characters due to an incorrect stripping process.
+ AliCollider::MakeEvent was updated accordingly to make use of this new memberfunction.
+04-mar-2004 NvE Functionality of AliObjMatrix extended to provide the number of references and
+ (row,col) indices of all the occurrences of the stored objects.
+ Also an additional memberfunction AliObjMatrix::RemoveObject introduced to allow more
+ flexibility in specifying objects to be removed.
+09-mar-2004 NvE Additional memberfunction AliObjMatrix::RemoveObject renamed to RemoveObjects to prevent
+ confusion and ambiguity in usage.
+ Linking facility of AliSignal extended by enabling multiple links to a specific signal slot.
+ Also call to AliSignal::ResetLink changed to AliSignal::ResetLinks() in the dtor
+ of AliTrack to adopt the extended AliSignal linking facility and output in
+ AliTrack::ListAll() limited to only the referring signal slots to prevent long output lists.
+12-mar-2004 NvE Additional "cout << endl;" in front of AliCollider initialisation message in order to always
+ have the initialisation message starting on a new line. On some systems the fortran
+ carriage control of the pure Pythia doesn't get treated correctly.
+04-apr-2004 NvE SetMass() invoked from AliTrack::Set3Momentum to get also the energy properly initialised.
+09-apr-2004 NvE Support for specification of unit scale introduced in AliPosition.
+19-apr-2004 NvE Memberfunction GetPrimed introduced for Ali3Vector.
+04-may-2004 NvE Various memberfunctions declared "const" to satisfy the strict Alice coding rules
+ and also to allow better compiler optimisation.

+02-jun-2004 NvE Memberfunction GetUnprimed introduced for Ali3Vector.
+17-jun-2004 NvE New class AliHelix introduced and "macgcclib" added to create ralice libs on MAC.
+24-jun-2004 NvE Coefficient kp7 changed from 7.4e-5 to 7.4e-6 in AliMath::BesselK0 to correct typo
+ (thanks Josh de Bever).
+ Typos corrected (i.e. abs() replaced by fabs() in several places) in AliHelix
+ to satisfy the Intel compiler (thanks Fons Rademakers).
+25-jun-2004 NvE Protection introduced in AliSignal::GetNlinks.
+29-jun-2004 NvE New class AliDevice introduced.
+ New memberfunctions and datamembers introduced in AliEvent to support investigation
+ and ordering of hits of various (classes of) devices.
+01-jul-2004 NvE AliCalorimeter derived from AliDevice to extend functionality (e.g. allow definition
+ of sets of calorimeters and investigate all the hits of a certain set via the
+ AliEvent structure). To prevent matrix swapping restrictions, the memberfuctions
+ SetSwapMode and GetSwapMode of AliCalorimeter have been renamed to SetMatrixSwapMode
+ and GetMatrixSwapMode, respectively.
+ Examples in the AliEvent.cxx documentation updated accordingly.
+ Backward links reset for non-owned hits in AliDevice destructor.
+06-jul-2004 NvE AliCalorimeter hit I/O only via the linear array to decrease filesize on disk
+ and improve I/O speed.
+ Internal temp. arrays used for hit sorting in AliDevice and AliEvent and array
+ pointers returned instead of the arrays themselves. This will provide more
+ flexibility in usage.
+ Sorting and clustering procedures in AliCalorimeter modified to use TObjArray pointers
+ to enable direct use of the AliDevice linear sorting facility.
+ Default for AliDevice changed such that now all registered hits are by default owned
+ by the AliDevice object.
+06-oct-2004 NvE Full support for data access via slotname specification introduced in AliAttrib and AliSignal.
+07-oct-2004 NvE Docs of AliAttrib and AliSignal updated for new data access via slotname specification.
+12-oct-2004 NvE Display facility introduced in AliDevice and device backward linking updated for
+ new "owning device" in AliSignal.
+13-oct-2004 NvE Hit investigation facilities extended in AliDevice and AliEvent.
+15-oct-2004 NvE Optimisation of MC parameters for nucleus-nucleus and astrophysics processes introduced
+ in AliCollider. Also facilities added to provide full user control.
+26-nov-2004 NvE Printout of UniqueID added in AliSignal::Data() and AliEvent::ShowDevices() in view of
+ addressing specific signals or devices during data analysis.
+ Memberfunction GetIdHit introduced in AliDevice and AliEvent and AliJet::GetIdTrack
+ optimised for speed.
+ Memberfunction GetIdDevice introduced in AliEvent.
+27-nov-2004 NvE Protection for j<1 introduced in AliSignal::SetWaveform().
+ The waveforms in AliSignal have now become completely decoupled from signal slots,
+ so support for setting waveforms by specifying a slotname has been removed.
+ Printout info in AliSignal::Data() and AliSignal::List() improved and memberfunctions
+ ListWaveform() and GetWaveformIndex() introduced in AliSignal.
+28-nov-2004 NvE User definable status word introduced in AliDevice to allow indication of different
+ versions of readout electronics etc...
+29-nov-2004 NvE Additional sub-directories (e.g. wa98) introduced which contain Ralice implementations
+ to serve data analysis efforts for various experiments.
+01-dec-2004 NvE Install scripts like e.g. "gcclib" renamed to "gcclib.sh" etc... in /scripts.
+ The old scripts (i.e. without the .sh extension) will be deleted in due time.
+12-jan-2005 NvE Bug fix in AliAttrib::GetSlotIndex() by exiting as soon as matching name is found.
+20-jan-2005 NvE Modification in AliSignal::GetNwaveforms() to return last index instead of array
+ size to take into account the fact that a TObjArray always gets a default size
+ of 16 when reading data from a file.
+ Also the standard ROOT file libNew.lib is now automatically renamed to libNew.lix
+ in the Ralice windows installation script mklibs.bat to prevent linking with
+ this libNew.lib which is inconsistent with the binary ROOT executable release.
+09-feb-2005 NvE New class AliTimestamp introduced to support timestamp information for
+ astrophysical research (i.e. Julian dates etc...) without the restrictions
+ of class TTimeStamp.
+10-feb-2005 NvE AliEvent modified such that it is derived from AliTimestamp.
+ This will allow events to be synchronised with astrophysical phenomena without
+ the restrictions imposed by TTimeStamp.
+ All existing user functions have been kept to provide full backward compatibility
+ in usage. However, a side effect of the new structure is that when reading data files
+ containing the old event structures, the original date/time stamp information is lost and
+ replaced by the date/time at the moment of reading the data.
+ This implies that to restore the original event date/time, the data files have to
+ be re-created. This I/O backward incompatibility could not be avoided in the
+ effort of eliminating the TTimeStamp restrictions.
+04-mar-2005 NvE Installation scripts named amdgcclib.sh introduced in all /scripts directories to enable
+ shared library creation on AMD 64 (Athlon and Opteron) machines.
+31-mar-2005 NvE AliObjMatrix derived from TNamed instead of from TObject to allow specification of
+ a name and title for this class.
+13-apr-2005 NvE New memberfunctions SetFitDetails and GetFitDetails introduced in AliTrack
+ to enable a versatile facility to store details of various fit procedures
+ for a certain track. This new facility is based on the original idea of Adam Bouchta.
+ Destructor of AliSignal modified to remove the corresponding AliSignal instance
+ first from all related tracks before deleting the link matrix area.
+14-apr-2005 NvE Functionality of ShowDevices extended in AliEvent. Also memberfunction HeaderData() modified
+ to prevent long output lists when many devices (and/or tracks) are present.
+ New memberfunction ShowTracks introduced in AliJet and memberfunction Data() updated.
+18-apr-2005 NvE New memberfunction GetTracks introduced in AliJet to provide various track selections.
+19-apr-2005 NvE Memberfunctions GetNtracks and GetTracks of AliJet extended in functionality.
+20-apr-2005 NvE Id of owning device added to the output of AliSignal::Data().
+10-may-2005 NvE Support for timestamps introduced in AliTrack and AliPosition.
+ Memberfunction GetX introduced in Ali3Vector for easy component access.
+ Picosecond support and calculation of time difference introduced in AliTimestamp
+ to enable investigation of both very short (i.e. time of flight analysis in
+ particle physics experiments) and very long (i.e. astrophysical phenomena)
+ time intervals.
+17-may-2005 NvE Functionality of AliTimestamp extended w.r.t. treatment of time intervals and
+ accuracy bug fixed in the calculation of time difference.
+19-may-2005 NvE AliTimestamp* pointer arguments supported in AliTimestamp::GetDifference for convenience
+ when investigating e.g. TOF or trigger times for tracks and/or hits in analysing
+ AliEvent structures.
+ Also GetMJD() invoked in GetDifference to ensure to always have updated Julian parameters.
+22-may-2005 NvE Class AliMath extended to provide full distribution functions of several standard
+ distributions (e.g. Binomial, Poisson, Gauss) and key statistics (e.g. Chi-squared,
+ Student's T, F-test) in view of analysis using Bayesian logic.
+ The various distributions are provided as TF1 objects.
+ In addition, functions to provide the P-values of the various key statistics are also
+ introduced to allow a classical frequentist analysis as well.
+25-may-2005 NvE Declaration of unused variable pi removed in AliMath::StudentDist and explicit double
+ specification of integer first argument to pow() in AliMath::FratioPvalue in order
+ to prevent messages from the gcc compiler (thanks Dipo, Philippe and Peter).
+02-jun-2005 NvE Bug fix in copy ctor of AliPosition and beginpoint etc... setting of AliTrack.
+ In AliTrack all points are now set after first deleting the existing AliPositionObj
+ object instead of using the Ali3Vector::Load() memberfunction.
+ The bug arose because of the extension of AliPosition with the possibility to
+ store an AliTimestamp. This made AliPosition differ from Ali3Vector w.r.t. datamembers.
+ Also "cout << endl;" introduced after the Pylist() call in AliCollider in order to
+ separate the Pythia event listing from subsequent output due to the mis-interpretation
+ of Fortran carriage-control characters on some systems.
+17-jun-2005 NvE New class AliJob introduced to provide a flexible (physics) analysis environment.
+ Bug (forgotten ps transfer in AliTimestamp::SetTJD) fixed (thanks Federico Carminati).
+22-jun-2005 NvE Specific job folder recursively removed from the generic AliJob folder environment
+ in the AliJob destructor before actually deleting the specific job folder itself.
+ Also main object pointer updated in case of a match with removal of object(s) from
+ the specific job environment.
+23-jun-2005 NvE Creation of specific job folder made optionally in AliJob.
+24-jun-2005 NvE Selection/overruling of specific job folder creation introduced in AliJob::ExecuteJob
+ and the AliJob (derived) instance explicitly removed from the ListOfTasks to prevent
+ ROOT crashing when closing after execution.
+02-aug-2005 NvE Support for explicit (de)calibration functions introduced in AliAttrib.
+03-aug-2005 NvE AliSignal::GetSignal has been extended to support various (de)calibration facilities.
+ Printout is now also provided in AliSignal::List when only calibration data exist
+ for AliDevice (or derived) objects.
+05-aug-2005 NvE Typos fixed in AliAttrib::GetCalFunction and AliAttrib::GetDecalFunction which
+ erroneously always returned a null pointer.
+10-aug-2005 NvE AliSignal::GetSignal extended with mode=8 to support dead flag of parent device
+ in conjunction with the dead flag of the signal itself.
+07-oct-2005 NvE Support for the extended AliSignal::GetSignal (de)calibration facilities
+ introduced in memberfunctions SortHits, GetExtremes, Displayhits and SortDevices
+ of classes AliDevice and AliEvent.
+ Note : For DisplayHits this new signal correction mode replaces the marker style
+ specification parameter.
+ Also new memberfunction GetDevices introduced in AliEvent.
+11-oct-2005 NvE SetMJD invoked at the end of AliTimestamp::Add instead of just updating the
+ various datamembers. In this way the TTimeStamp parameters are brought in sync
+ with the (modified) AliTimestamp values.
+20-oct-2005 NvE Directory /macros introduced and ROOT macro makedocs.cc added in /macros
+ to provide a generic method to auto-create the html class documentation
+ on all supported platforms.
+ For further details see /macros/makedocs.cc.
+24-oct-2005 NvE Protection introduced in AliJet::AddTrack to prevent multiple storage of
+ the same track in case no private copy of the track is made.

+ for Ali4Vector.
+ Also memberfunction SortJets introduced in AliVertex.
+ Misleading comment modified in AliDevice.cxx.
+29-oct-2005 NvE Forgotten angular unit setting fixed w.r.t. begin point etc... in AliTrack::ListAll
+ ad begin point etc... info also added in AliTrack::List.
+ Memberfunction SortTracks introduced in AliJet and comment corrected in AliVertex.h.
+07-nov-2005 NvE Macro makedocs.cc in directory /macros modified (i.e. ";" changed by ":") to make
+ it generic so that it works correctly on all platforms (thanks Axel Naumann).
+08-nov-2005 NvE Sorting memberfunctions in AliDevice, AliVertex and AliJet optimised to save
+ CPU time. In case two values are identical no swap is performed.
+ Basically the test "val1 < val2" was replaced by "val1 <= val2".
+09-nov-2005 NvE DisplayHits memberfunctions in AliDevice updated to fully support all
+ (de)calibration modes of GetSignal for displaying (and skipping dead) hits.
+14-nov-2005 NvE Hit access by name introduced in AliDevice.
+15-nov-2005 NvE Support for opening angle calculation between a 3-vector and the 3-vector part

+14-mar-2006 NvE RemoveTracks() facilities introduced in AliJet.
+17-mar-2006 NvE Support for marker of track starting point introduced in AliHelix.
+ This allows observation of moving direction in event displays.
+ Also support for ignoring track endpoints introduced in AliHelix to
+ allow correct display for very long tracks together with observed hits.
+18-mar-2006 NvE Support for display of selected track array introduced in AliHelix.
+ Also copy ctor of AliHelix made complete for new datamembers.
+22-mar-2006 NvE Line attribute selections for displays extended in AliHelix.
+20-apr-2006 NvE Several small modifications to prevent gcc warnings.
+10-may-2006 NvE Distance determination between tracks and/or jets introduced in
+ AliTrack and AliJet.
+ Also compiler warnings activated for overloaded virtuals in installation
+ script for AMD Athlon in the /scripts sub-directory.
+22-jun-2006 NvE Linear track storage facility introduced in AliSignal to enable
+ a lightweight signal <-> track backward linking facility instead of
+ the elaborate signal slot related links.
+ Also the functionality of AliTrack::AddSignal extended with specific modes.
+ Double_t replaced by Double32_t in Ali3Vector.h, Ali4Vector.h and AliBoost.h
+ and fDresult suppressed for I/O streaming. This will reduce the produced
+ output filesize.
+21-jul-2006 NvE AliSample extended for computation of median.
+12-sep-2006 NvE Memberfunctions GetNslots and AddNamedSlot introduced and various
+ modifications made in AliAttrib and AliSignal to overcome a ROOT
+ feature which always sets the size of TArray objects to a default
+ of 16 when reading these objects back from a file.
+ The modified AliAttrib and AliSignal don't rely on a GetSize()
+ anymore, but determine the number of stored values from the
+ actual array contents.
+19-sep-2006 NvE Accuracy problem solved in Ali3Vector::GetOpeningAngle.
+20-sep-2006 NvE AliSample::GetMedian corrected for empty or single value arrays.
+25-sep-2006 NvE AliSample extended with memberfunction GetSpread() and also
+ support for providing minimum and maximum values introduced.
+12-oct-2006 NvE New memberfunction GetNsignals introduced in AliJet and jet
+ ordering w.r.t. number of signals added in AliVertex.
+19-oct-2006 NvE AliJet::GetNsignals modified to prevent double counting of
+ multiple occurrences of the same signal.
+24-oct-2006 NvE AliJet and AliVertex extended with ordering w.r.t. charge.
+26-oct-2006 NvE Energy/Momentum scale indicator introduced in AliTrack and AliJet
+ and support for chi2 and ndf datamembers removed from AliTrack.
+ The latter can be achieved in a more flexible way via the fit
+ details facility of AliTrack.
+07-nov-2006 NvE Default unit scale changed from cm to meter in AliPosition
+ and support introduced for user selectable unit scale
+ in retrieval of position coordinates, errors and distances.
+08-nov-2006 NvE User selectable unit scale introduced for retrieval of
+ physics parameters and distances in AliTrack and AliJet.
+ Also the track and jet sorting memberfunctions of AliJet

+ Also AliHelix has been updated to use this new feature and the
+ default meter metric scale.
+09-nov-2006 NvE AliCollider updated to use new standard 1 meter metric units
+ and generator parameters stored in a device named "AliCollider".
+ Also beam/target datamembers removed from AliEvent and storage
+ of these beam/target parameters performed via a device named "Beam".
+10-nov-2006 NvE Bug fixed in AliHelix.cxx such that the original reference point
+ of the track itself is not modified when the user had specified
+ a different scale. Also GetLastPoint() used in AliHelix to obtain
+ the index of the last point instead of relying on the dimension
+ of the points array as obtained with GetN(). This increases the
+ accuracy of extrapolation (and drawing) resuls since no undefined
+ points are now used anymore.
+01-dec-2006 NvE AliTimestamp::Add() updated to allow specification of large time differences
+ also by giving e.g. only a certain number of seconds instead of explicitly
+ giving the time difference in elapsed days, remaining elapsed seconds etc...
+ This is very convenient by time manipulations based on GPS data.
+ The extension has been realised by just replacing the relevant if()
+ statements by while() loops in determining the remaining fractional counts.
+ Furthermore, some modulo operations have been introduced to prevent
+ integer overflows.
+08-dec-2006 NvE Memberfunctions SetUT introduced in AliTimestamp to provide convenient
+ ways to set a specific UT date/time.
+20-jan-2007 NvE AliMath extended with Nfac(), LnNfac() and LogNfac() facilities.

+ accessible even for cases which fall outside the TTimeStamp range.
+ As such, the UT and GST info will always be provided via the Date()
+ memberfunction.
+16-mar-2007 NvE Uniform data format introduced for printout of AliTimestamp::Date().
+17-mar-2007 NvE AliTimestamp extended to allow local time printout for a specified offset
+ and addition of a time difference specified as (fractional) hours.
+ Also bug fixed in the fractional hour conversion facility.
+20-mar-2007 NvE Support for retrieval of Local Time (LT) and Local Sidereal Time (LST)
+ introduced in AliTimestamp.
+22-mar-2007 NvE Support introduced for setting of timestamp parameters based on Local Time (LT)
+ 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

+ 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.

+ 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.
