Class Description

                                                                      
 TFriendElement                                                       
                                                                      
 A TFriendElement TF describes a TTree object TF in a file.           
 When a TFriendElement TF is added to the the list of friends of an   
 existing TTree T, any variable from TF can be referenced in a query  
 to T.                                                                
                                                                      
 To add a TFriendElement to an existing TTree T, do:                  
       T.AddFriend("friendTreename","friendTreeFile");               
                                                                      
  see TTree::AddFriend for more information

 if treename is of the form "a=b", an alias called "a" is created for treename = "b"
 by default the alias name is the name of the tree.
