/** \class PndDchCylinderHitProducer
 *  \author A.Wronska <aleksandra.wronska@uj.edu.pl>
 *  \date 26/03/08
 *  \brief Class for conversion digis to spatial cylinder hits
 * 
 * This task converts electronic information from the detector
 * (i.e. digis) into spatial information in form of a a cylinder
 * (PndDchCylinderHit): wire position in the plane, plane's z-position and 
 * rotation angle, distance to the wire (=radius of the cylinder).
