Trees

• I/O speed-up (thanks H1)

• TTree::BuildIndex

• new TreeViewer

• Automatic binning from TAxis. This solves a serious problem with TTree::SetEstimate

• Wildcardind in TTree::SetBranchStatus

• More symmetry between split and non-split modes

• Improved TTree::MakeClass (can still be improved)

• New functions TTree::CopyTree and TTree::CloneTree

• TBranchObject::SetAutoDelete
