/*! Represents a reconstructed particle track. It 
could be a charged particle track or a photon that is 
reconstructed due to it's conversion into an 
electron-positron pair. 

A track contains two lists:

1.) A list of TkrLocator objects which contain the position and angle of the 
    track at different interesting positions  (e.g.: initial point, exit point 
    of the tracker).

2.) A list of TkrHit objects which point to the TkrSiCluster objects that are associated with this track.
