///////////////////////////////////////////////////////////////////////
// AliFMDhit is the hit class for the FMD. Hits are the information
// that comes from a Monte Carlo at each step as a particle mass through
// sensitive detector elements as particles are transported through a
// detector.
//
// Data members:
//
// Int_t fTrack
//     See AliHit for a full description. The track number of the track
// that made this hit.
//
// Float_t fX
//     See AliHit for a full description. The global x position of the
// hit (in the standard units of the Monte Carlo).
//
// Float_t fY
//     See AliHit for a full description. The global y position of the
// hit (in the standard units of the Monte Carlo).
//
// Float_t fZ
//     See AliHit for a full description. The global z position of the
// hit (in the standard units of the Monte Carlo).
//
// Int_t fStatus
//     The track status flag. 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 fVolume
//     The number of the FMD detector that contains this hit. 

// Float_t fEdep
//     The energy lost by the particle during the step ending in this
// hit. The units are those determined by the Monte Carlo.
//
// Float_t fPx
//     The x momentum, in global coordinates, of the particle that
// "created" the hit at the time and position of the hit. The units
// are those determined by the Monte Carlo.
//
// Float_t fPy
//     The y momentum, in global coordinates, of the particle that
// "created" the hit at the time and position of the hit. The units
// are those determined by the Monte Carlo.
//
// Float_t fPz
//     The z momentum, in global coordinates, of the particle that
// "created" the hit at the time and position of the hit. The units
// are those determined by the Monte Carlo.
//
///
// Float_t fTime
//     The time of flight associated with the particle ending in this
// hit. The time is typically measured from the point of creation of the
// original particle (if this particle is a daughter).  The units
// are those determined by the Monte Carlo.
