 * Description:
 *
 *  A basic processor of simulated step hits in SuperNEMO calorimeter blocks.
 *
 *  This algorithm clusterizes Geant4 step hits belonging to calorimeter
 *  blocks. This object inherits most of the functionalities of the generic
 *  'calorimeter_step_hit_processor' from Bayeux/mctools library : it just
 *  overloads the search of block's geometry ID method by using geometry
 *  locators especially built for SuperNEMO.
 *
 *  CAUTION: this processor can manage only one geometry mapping category
 *  so care should be taken to attach only one geometry model (with the proper
 *  mapping category) to this processor.
