0005  * Base class for "reconstruction" geometries. Given the detId of a module,
0006  * the class has methods to access the corresponding module's DetLayer.
0007  * This base class returns always a dummy zero pointer to the DetLayers. Its
0008  * methods are virtual and are supposed to be overridden by Muon, Tracker
0009  * and Global concrete reconstruction geometries.
