0005  *
0006  *  A container of volumes in the barrel. It is part of the hierarchical
0007  *  organisation of barrel volumes:
0008  *
0009  *  A barrel layer (MagBLayer) groups volumes at the same distance to
0010  *  the origin. It consists of 12 sectors in phi (MagBSector).
0011  *  Each sector consists of one or more rods (MagBRods) of equal width in phi.
0012  *  Rods consist of one or more slabs (MagBSlab); each one consisting of one
0013  *  or, in few cases, several volumes with the same lenght in Z.
