Implement function TMultiGraph::RecursiveRemove.
When a TGraph is deleted (eg via the context menu), its parent TMultigraph
is notified to remove the TGrapg from its list of graphs.
Destructor protected.

Changes in the functions DistancetoPrimitive. Return immediatly in case
one of the sub-objects has already selected an object.
This may be the case with TPaveStats.

Add protections in case GetHistogram, GetXaxis, GetYaxis are called
and the fHistogram pointer is null. This situation can happen
when drawing a graph with no option or invalid options.

Add an optional argument to TMultiGraph::Draw.
This optional argument can be used to specify the draw option for this graph.
If a draw option is not specified, the option specified in TMultiGraph::Draw
will be used instead.

Also, always use the option "0" when painting the frame histogram.
The option "0" suppresses the drawing of the horizonthal line at y=0.

rename IOSFwd.h and IOStream.h to Riosfwd.h and Riostream.h. The change
is necessary because on Windows which is case insensitive IOStream.h
hides the real iostream.h.

use IOSFwd.h in headers instead of <iosfwd> or many other ifdef'ed variant
and IOStream.h in the source instead of <iostream[.h]>, <fstream[.h]> and
<iomanip[.h]>.

Modify the algorithm computing the minimum of all TGraphs and take into account
the case where the minimum is negative when an Unzoom happens on the y axis.

      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.

Add new class TMultiGraph.
//   A TMultiGraph is a collection of TGraph (or derived) objects
//   Use TMultiGraph::Add to add a new graph to the list.
//   The TMultiGraph owns the objects in the list.
//   Drawing options are the same as for TGraph
//   Example;
//     TGraph *gr1 = new TGraph(...
//     TGraphErrors *gr2 = new TGraphErrors(...
//     TMultiGraph *mg = new TMultiGraph();
//     mg->Add(gr1);
//     mg->Add(gr2);
//     mg->Draw("alp");
