/** \class PndGemTrackFinderIdeal
 *  \author R. Karabowicz <r.karabowicz@gsi.de>
 *  \date 19.03.2009
 *  \brief Ideal track finding algorithm
 * 
 *  Track finding procedure operates on mc data.
 *  Reads MC truth (MCTracks and MCPoints), creates
 *  one PndTrack for each MCTrack and attaches the hits according
 *	to the MCTrack of the corresponding MCPoint
