6// Class AliEMCALTrack
7// ---------------------
8// Implementation of a track to be used for EMCAL track matching.
9// This object is used to find track intersection with EMCAL surface
10// in order to find the most well matched EMCAL cluster to associate to it.
11// NO Kalman-like parameter updating is done.
