/** \class MagBSector
 *   
 *  A container of volumes in the barrel. It is part of the hierarchical 
 *  organisation of barrel volumes:
 *
 *  A barrel layer (MagBLayer) groups volumes at the same distance to
 *  the origin. It consists of 12 sectors in phi (MagBSector). 
 *  Each sector consists of one or more rods (MagBRods) of equal width in phi.
 *  Rods consist of one or more slabs (MagBSlab); each one consisting of one 
 *  or, in few cases, several volumes with the same lenght in Z.
