hi 


would be nice if one could pass a logical function as an argument in
CopyTree. E.g. in the example below i don't like the fact that i have to
hardwire the cut values where i would like to use variables. In addition
the selection might become more complicated. 

newtree =t->fTree->CopyTree("Chiprob>0.01&&Mass>5.129&&Mass<5.429");


cheers
