 TDSet                                                                
                                                                      
 This class implements a data set to be used for PROOF processing.    
 The TDSet defines the class of which objects will be processed,      
 the directory in the file where the objects of that type can be      
 found and the list of files to be processed. The files can be        
 specified as logical file names (LFN's) or as physical file names    
 (PFN's). In case of LFN's the resolution to PFN's will be done       
 according to the currently active GRID interface.                    
 Examples:                                                            
   TDSet treeset("TTree", "AOD");                                     
   treeset.Add("lfn:/alien.cern.ch/alice/prod2002/file1");            
   ...                                                                
   treeset.AddFriend(friendset);                                      
                                                                      
 or                                                                   
                                                                      
   TDSet objset("MyEvent", "*", "/events");                           
   objset.Add("root://cms.cern.ch/user/prod2002/hprod_1.root");       
   ...                                                                
   objset.Add(set2003);                                               
                                                                      
 Validity of file names will only be checked at processing time       
 (typically on the PROOF master server), not at creation time.        
                                                                      

 Create a TDSet element.

 copy constructor

 Clean up the element.

 Return object name.

 Return directory where to look for object.

 Print a TDSetElement. When option="a" print full data.

 Validate by opening the file.

 Validate by checking against another element.

Compare elements by filename (and the fFirst).

 Add friend TDSetElement to this set. The friend element will be copied to this object.

 Deletes the list of friends and all the friends on the list.
