      Add new option to run with parallel unzipping in a separate thread.
To run it do
  Event 5000 1 99 1    (to write the file Event.root)
  Event 5000 1 99 20   (to read normal without a thread)
  Event 5000 1 99 21   (to read with the parallelp unzipping thread)
Send the results to rootdev@root.cern.ch

      A) Support for top level STL Containers.  You can now do
   list<int> *ptr = new list<int>;
   tree->Branch("mystl","list<int>",&ptr);

B) Autodetection of the pointer type passed to the branch constructor.
So you can now do:
   list<int> *ptr = new list<int>;
   tree->Branch("mystl",&ptr);

C) Check of the type of the pointer type passed to the branch constructor.
So that you now get an error:
   list<int> *ptr = new list<int>;
   tree->Branch("mystl","list<float>",&ptr);

Error in <TTree::Branch>: The class requested (list<float>) for the branch
"mystl" is different from the type of the pointer passed (list<int>)

D) TTree's SetBranchAddress now also check its input address (unless the
user explicitly specify (char*) or (void*).

Test/Event and the tree tutorials have been updated to take advantage of the
new syntax.

      Modify the test program to illustrate the new classes TRef and TRefArray. · 549b0ea1
      Rene Brun authored 
      The following members have been added to Event.h
   TRefArray     *fHighPt;       //array of High Pt tracks only
   TRefArray     *fMuons;        //array of Muon tracks only
   TRef           fLastTrack;    //pointer to last track

In MainEvent (write part) the two arrays are filled in the loop
making the tracks. fLastTrack is set directly in AddTrack.

Split mode can be used to store in separate branches the original
tracks and the two selected track arrays. Only one copy of a track
is stored in the file. When the file is read back, one can read
in any order the TClonesArray of tracks or the other arrays.
If the array fMuons is read and the TClonesArray branches are not
read, fMuons->At(i) will return 0. When the TClonesArray is read,
fMuons->at(i) will return a pointer to the selected track number i
in the TRefArray fMuons. This will point directly to one of the
tracks in the TClonesArray.

Note that the branches fHighPt, fMuons and fLastTrack could also
be stored in separate files (may be friends of the master file).
