20// Base class for ALICE modules. Both sensitive modules (Modules) and //
21// non-sensitive ones are described by this base class. This class //
22// supports the hit and digit trees produced by the simulation and also //
23// the objects produced by the reconstruction. //
24// //
25// This class is also responsible for building the geometry of the //
26// Modules. //
