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
pecified as logical file names (LFN's) or as physical file name
(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.
