Class Description

                                                                      
 TPacketizer2                                                         
                                                                      
 This class generates packets to be processed on PROOF slave servers. 
 A packet is an event range (begin entry and number of entries) or    
 object range (first object and number of objects) in a TTree         
 (entries) or a directory (objects) in a file.                        
 Packets are generated taking into account the performance of the     
 remote machine, the time it took to process a previous packet on     
 the remote machine, the locality of the database files, etc.
