/** \class BlockClasses
 *
 *  Initialization of static fgCompare functions. At the moment a number of 
 *  functions TCompare*** are implemented (see BlockCompare.h). 
 *  Function TCompareXX sorts objects 
 *  by the variable "XX" that MUST be present in the data members of the 
 *  Block TRoot class.
 *  By default most objects are sorted by PT or ET.
 *  Only calorimeter cells and basic cluster are sorted by E
 *  TRootGenParticle particle is not sorted by default
 *  to preserve mother-dautherlinks between particles.
