-//
-// AliITS is the general base class for the ITS. Also see AliDetector for
-// futher information.
-//
-// Data members:
-//
-// AliITSgeom *fITSgeom
-// All of the geometry information about the active volumes that
-// make up the ITS are described in the AliITSgeom class. This includes
-// the transformation functions between the local and global coordinate
-// systems and the like. See the full description found in the AliITSgeom
-// class. Here in the AliITS class is kept the pointer to the geometry
-// used in the simulations or that thought to be the correct one for the
-// data. Until a more general class is define and a more appropriate
-// place is found to keep this geometry information, it is kept here in
-// AliITS.
-//
-// TObjArray *fITSpoints
-// This is a pointer to the points, to be used by the tracking algorithms
-// for example, found in the detectors of the ITS. To allow for the most
-// general points structure it is defined to be a pointer to a TObjArray where
-// each array element would be one point found in the ITS detectors. An
-// Addpoints function is defined below. By default an array of 16 TObjects are
-// defined during the initialization of AliITS. This is automatically expanded
-// when necessary by the Addpoints function.
-//
-// Bool_t fEuclidOut
-// This is a flag used to indicate that an Euclid compatible CAD
-// file will be created upon the creation of the ITS Monte Carlo
-// geometry definition, in the function CreatGeometry. If fEuclidOut is
-// true, then a file called ITSgeometry.euc will be created.
-//
-// Int_t fIdN
-// This variable contains the number of layers defined in the ITS
-// geometry. It is primarily used as a size indicator for fIdSens and
-// fIdName described below. In general the number of layers, ladders, or
-// detectors should be gotten from the AliITSgeom functions. Upon
-// creating the AliITS object it is set to zero.
-//
-// Int_t *fIdSens
-// This is a pointer to an array containing the Monte Carlo volume
-// numbers for the different layers of the ITS. These numbers are needed
-// by the StepManager function to determine what layer a hit was on. It
-// is sized and initialized in the Init function and the AliITSv? Init
-// function, called after a call to CreateGeometry. Upon creating the
-// AliITS object it points to zero. This variable is made a pointer
-// in order to keep the maximum flexibility at this level of the code.
-//
-// char **fIdName
-// This is a pointer to an array of characters containing the names of
-// the different ITS layers as defined in the Monte Carlo geometry data-
-// base. It is sized and filled in the AliITSv? Init function, called
-// after a call to CreatGeometry. Upon creating the AliITS object it
-// points to zero. This variable is make a pointer in order to keep the
-// maximum flexibility at this level of the code.
-//
-// Member Functions:
-//
-// AliITS()
-// The default constructor of the AliITS class. In addition to
-// creating the AliITS class it zeros the variables fIshunt (a member
-// of AliDetector class), fEuclidOut, and fIdN, and zeros the pointers
-// fITSpoints, fIdSens, and fIdName. The AliDetector default constructor
-// is also called.
-//
-// AliITS(const char *name, const char *title)
-// The constructor of the AliITS class. In addition to creating the
-// AliITS class, it allocates memory for the TClonesArrays fHits and
-// fDigits, and for the TObjArray fITSpoints. It also zeros the variables
-// fIshunt (a member of AliDetector class), fEuclidOut, and fIdN, and zeros
-// the pointers fIdSens and fIdName. To help in displaying hits via the ROOT
-// macro display.C AliITS also sets the marker color to red. The variables
-// passes with this constructor, const char *name and *title, are used by
-// the constructor of AliDetector class. See AliDetector class for a
-// description of these parameters and its constructor functions.
-//
-// ~AliITS()
-// The default destructor of the AliITS class. In addition to deleting
-// the AliITS class it deletes the memory pointed to by the fHits, fDigits,
-// fIdSens, fIdName, and fITSpoints.
-//
-// AddHit(Int_t track, Int_t *vol, Float_t *hits)
-// The function to add information to the AliITShit class. See the
-// AliITShit class for a full description. This function allocates the
-// necessary new space for the hit information and passes the variable
-// track, and the pointers *vol and *hits to the AliITShit constructor
-// function.
-//
-// AddDigit(Int_t *track, Int_t *digits)
-// The function to add information to the AliITSdigits class. See the
-// AliITSdigits class for a full description. This function allocates the
-// necessary new space for the digits information and passes the pointers
-// *track and *digits to the AliITSdigits constructor function.
-//
-// BuildGeometry()
-// This function builds a simple ITS geometry used by the ROOT macro
-// display.C. In general the geometry as coded is wrong.
-//
-// CreateGeometry()
-// This function builds the detailed geometry used by the Geant
-// Monte Carlo. As defined here it is a dummy routine to be replaced
-// by the version coded up in AliITSv? where the specific geometry to
-// be used by the simulation is defined. See the definition of AliITSv5
-// or the other routines for a complete definition.
-//
-// CreateMaterials()
-// This function defines the default materials used in the Geant
-// Monte Carlo simulations. In general it is automatically replaced by
-// the CreatMaterials routine defined in AliITSv?. Should the function
-// CreateMaterials not exist for the geometry version you are using this
-// one is used. See the definition found in AliITSv5 or the other routine
-// for a complete definition.
-//
-// IsVersion()
-// Returns the version number of the AliITS class. At present it is
-// version 1.
-//
-// DistancetoPrimitive(Int_t x, Int_t y)
-// A dummy routine used by the ROOT macro display.C to allow for the
-// use of the mouse (pointing device) in the macro. In general this should
-// never be called. If it is it returns the number 9999 for any value of
-// x and y.
-//
-// Init()
-// This routine initializes the AliITS class. It is intended to be called
-// from the Init function in AliITSv?. Besides displaying a banner
-// indicating that it has been called it initializes the array fIdSens.
-// Therefore it should be called after a call to CreateGeometry.
-//
-// MakeBranch(Option_t *Opt=" ")
-// Creates the TTree branch where the class AliITS is kept.
-//
-// SetEUCLID(bool_t euclid=1)
-// Sets the flag fEuclidOut to true (default) of false (euclid=0).
-// By setting or clearing the fEuclidOut flag you can controls whether
-// or not a euclid formatted output file of the ITS geometry is written.
-// If fEuclidOut is set true then a file called ITSgeometry.euc will be
-// written after the ITS geometry is defined in the Monte Carlo. If
-// fEuclidOut is set false then no file is created.
-//
-// StepManager()
-// Dummy routine which is replaced by the routine StepManager() defined
-// in AliITSv?. If no such routine exist then this routine returns zero.
-// See AliITSv? for a detailed description of the step manager routines.
-//
-// GetITSgeom()
-// Returns the value of the pointer fITSgeom. This is used to get
-// access to the ITS geometry stored in the file. See AliITSgeom for a
-// full description of the geometry package.
-//
-// GetITSpoints()
-// Returns the value of the pointer fITSpoints. This is used to get
-// access to the ITS cluster objects, if filled, stored in the file. See
-// AliITSCluster for a full description of the cluster data.
