/** \class BarrelDetLayer
 *  A specialization of the DetLayer interface for barrel layers.
 *  Barrel layers are cylinders with their axes parallel to 
 *  the global Z axis.
 *  The methods that have a common implementation for all BarrelDetLayers
 *  are implemented in this class,
 *  but some methods are left abstract.
