/** \class TrackingGeometry
 *
 *  Base class for the geometry of tracking detectors.
 *  A geometry contains both the GeomDetUnit s and bigger composite 
 *  structures, which are concrete GeomDet s.
 *
 *  There are therefore 2 kind of methods in the interface: 
 *   - the generic ones, i.e.
 *  dets(), detIds(), idToDet(), do not distinguish between 
 *  GeomDet and GeomDetUnit, and can be used blindly for the typical use
 *  of accessing the reference frame transformation of the det. 
 *   - Those specific to GeomDetUnit s, i.e. detUnits(),  detUnitIds(), 
 *  idToDetUnit(), are useful when it is necessary to deal with the 
 *  extended interface of GeomDetUnit.
