Detailed Description

A propagator which use different algorithm to propagate inside or outside tracker

Author: Stefano Lacaprara - INFN Padova author Chang Liu - Purdue University

Modification: 26-Jun-2002 SL: theTkVolume is now a static ReferenceCountingPointer<BoundCylinder> 28-Aug-2002 SL: added methods to unhide Propagator methods 29-Oct-2002 SL: fixed clone and copy constructor, and BoundCylinder are build with CylinderBuilder to enforce the referencePointer
