//  fVrho    :      rho-coordinate of the Vertex
//  fFirst   :      =1 for the first hit of the track, =0 otherwise

// Description: dummy hit class used in reconstruction (derived from AliHit)
// For a given TOF hit, the class contains:
// - the distance to the nearest hit
// - flag for first or second track crossing
// - number of the track which produced the hit
// - flag for noise
