From Gerri:
This is the last patch to synchronize with the CAF:
TDSet.h, .cxx
- Use TCollection instead of TList
- Support thre object types in TDSet::Add(TCollection *): TFileInfo, TUrl
and TObjString .
- Conserve the looked-up status of TChainElements when instantiating
from a TChain.
TChainElement.h, .cxx
- Use BIT(15) to flag the looked-up status
TChain.h, .cxx
- Use TCollection instead of TList
- Support thre object types in TDSet::Add(TCollection *): TFileInfo, TUrl
and TObjString .
- Save / Test the looked-up status of elements to avoid multiple lookup;
an option is available in TChain::Lookup(Bool_t force = kFALSE) to
force a new lookup.

Enhance SetBranchAddress so that the curent recommended code:
chain->SetBranchAddres(branchname,&userdata); // once per chain
....
branchptr = chain->GetBranch(branchname); // once per tree in the chain
can be replaced by:
chain->SetBranchAddres(branchname,&userdata,&branchptr); // once per chain
As a result, branchptr will be either set to 0 when the branch does
not exist or the tree is not loaded yet and will be 'refreshed'
automatically everytime the chain loads a new tree.
MakeClass and MakeSelector have been updated to take advantage of
this new feature. This removed most the code from the Notify
method.

From Marek Biskup:
major new PROOF developments:
- access to PROOF directly via the TChain interface (creating a TDSet
in the background).
- access to PROOF based trees via the TTreeViewer
- fully implemented the TChain/TDSet::Draw() interface.
- PROOF sessions can now be browsed via the TBrowser

From Philippe:
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.

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.
