TTreeViewer::TTreeViewer(const TTree *tree)

This new constructor is called by TTreePlayer::StartViewer.
This new constructor solves a problem reported by Ole Streicher
 TFile *f = new TFile("Header.root")
 TTree *p = f->Get("Physics");
 p->StartViewer()
 TFile *g = new TFile("Tracker.root")
 p->StartViewer()
