////////////////////////////////////////////////////////////////////////
// Version: 0
// Written by Rene Brun, Federico Carminati, and Roberto Barbera
// are those determined by the Monte Carlo.
//
//
-// Member functions:
-//
-// AliITShit()
-// The default creator of the AliITShit class.
-//
-// AliITShit(Int_t shunt, Int_t track, Int_t *vol, Float_t *hits)
-// The creator of the AliITShit class. The variables shunt and
-// track are passed to the creator of the AliHit class. See the AliHit
-// class for a full description. the integer array *vol contains, in order,
-// fLayer = vol[0], fDet = vol[1], fLadder = vol[2], fStatus = vol[3].
-// The array *hits contains, in order, fX = hits[0], fY = hits[1],
-// fZ = hits[2], fPx = hits[3], fPy = hits[4], fPz = hits[5],
-// fDestep = hits[6], and fTof = hits[7].
-//
-// ~AliITShit()
-// The default destructor of the AliITShit class.
-//
-// int GetTrack()
-// See AliHit for a full description. Returns the track number fTrack
-// for this hit.
-//
-// SetTrack(int track)
-// See AliHit for a full description. Sets the track number fTrack
-// for this hit.
-//
-// Int_t GetTrackStatus()
-// Returns the value of the track status flag fStatus. This flag
-// indicates the track status at the time of creating this hit. It is
-// made up of the following 8 status bits from highest order to lowest
-// order bits
-// 0 : IsTrackAlive(): IsTrackStop():IsTrackDisappeared():
-// IsTrackOut():IsTrackExiting():IsTrackEntering():IsTrackInside() .
-// See AliMC for a description of these functions. If the function is
-// true then the bit is set to one, otherwise it is zero.
-//
-// Int_t GetLayer()
-// Returns the layer number, fLayer, for this hit.
-//
-// Int_t GetLadder()
-// Returns the ladder number, fLadder, for this hit.

-// Returns the layer, ladder, and detector numbers, fLayer fLadder fDet,
-// in one call.
-//
-// Float_t GetIonization()
-// Returns the energy lost, fDestep, by the particle creating this hit,
-// in the units defined by the Monte Carlo.
-//
-// GetPoositionG(Float_t &x, Float_t &y, Float_t &z)
-// Returns the global position, fX fY fZ, of this hit, in the units
-// define by the Monte Carlo.
-//
-// Float_t GetTOF()
-// Returns the time of flight, fTof, of this hit, in the units defined
-// by the Monte Carlo.
-//
-// GetPositionG(Float_t &x, Float_t &y, Float_t &z, Float_t &tof)
-// Returns the global position and time of flight, fX fY fZ fTof, of
-// this hit, in the units define by the Monte Carlo.
-//
-// GetPositioonP(Float_t &px, Float_t &py, Float_t &pz)
-// Returns the global momentum, fPx fPy fPz, of the particle that made
-// this hit, in the units define by the Monte Carlo.
