/** \class BlockClasses
 *
 *  Definition of classes to be stored in root tree.  
 *  You can decide to have the objects in each event to be sorted according 
 *  to one of the data member of the class. If you decide so then a class 
 *  inheriting from class TCompare should be implemented. 
 *  There are already several functions TCompare*** 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.
