/** \class PndDchTrackFinder
 *  \author A.Bubak <arkadiusz.bubak@gmail.com>
 *  \date 27.01.2008
 *  \brief Abstract base class for concrete Dch track finding algorithm.
 * 
 *  Each derived class must implement the method DoFind. This has
 *  to operate on the TClonesArrays of Pnd hits/digis and to fill
 *  the PndDchTrackArray.
