Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

From Olivier and me:
Split the TGraph classes to move the graphics code to separate classes.
These classes will be moved to the hist directory once the classes will be ok.
The TGraphs are painted via the TVirtualGraphPainter class and its concrete
implementation TGraphPainter.
At the difference of the TH1 classes for which a different painter is created
when drawing each histogram, one single TGraphPainter class is created.
The TGraphPainter class does not have internal state, all the information
from TGraph is passed to the drawing functions via parameters.

from Axel:
Change the signature of SavePrimitive from
void SavePrimitive(ofstream &out, Option_t *option);
to
void SavePrimitive(ostream &out, Option_t *option = "");
With this change one can do, eg
myhist.SavePrimitive(std::cout);
WARNING: do rm -f tree/src/*.o

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Anna Kreshuk:
- TLinearFitter class: Linear fitter is used to fit a set of data points with a linear
combination of specified functions (with or without weights). The "linear" in the name
stands for "linear in parameters", not variables. The main advantages,
compared to a general non-linear fitter, is that the linear fitter is considerably
faster and doesn't require setting the initial values of parameters.
The linear fitter can be used directly or through TH1::Fit and TGraph::Fit functions
When it's used directly, functions of more than 3 dimensions can be fitted.
- TFormula: a new data member fLinearParts and methods to process it are added. Now
one can create a function of the type that can be fit by the linear fitter.
Example: TFormula f("f", "x++sin(x)") is equivalent to
TFormula f("f","[0]*x + [1]*sin(x)"), but if a TH1::Fit or a TGraph::Fit is performed
with the 1st formula, it goes through the linear fitter, if it's performed with the
2nd formula, it goes through Minuit.
- TMultiGraph class: the Fit method is implemented, allowing to fit all the graphs
of a multigraph simultaneously
- TGraph, TGraphErrors, TGraphAsymmErrors, TGraphBentErrors - functions GetEXhigh(),
GetEXlow(), GetEYhigh(), GetEYlow() implemented to simplify the GraphFitChisquare()
function of the TFitter class
- TH1, TGraph, TGraph2D, TMultiGraph - changes in the Fit functions, allowing to use
the linear fitter. Fitting with "polN" functions redirected to use the linear fitter,
in cases where no options, except "range", are specified.

Implement a new TGraphAsymErrors constructor taking two histograms
in input. The resulting graph is obtained by dividing the two histograms.
The asymmetric errors are computed by the new function BayesDivide.
A new set of small utility functions (origin Marc Paterno) is introduced
in the class.
Code originally proposed by Andy Haas.

Add new functions to all the TGraph classes to interactively with the mouse
add a new point or remove a point. These new functions are available
from the context menu.
Int_t InsertPoint();
Int_t RemovePoint();
Add new function SetPointError in TGraphErrors and TGraphAsymmErrors.
This new function is also in the context menu.

In all the TGraphX classes add a new method Apply suggested and implemented by
Miroslav Helbich <helbich@mail.desy.de>
If one has points x,y of TGraph, sometimes it is convenient to apply a
function to those points e.g y=f(x,y). There are few examples I've been
dealing with, like scale the points by some number f(x,y)=y*scale factor
or if you try to fit some complicated formula it is sometimes better to do
the transformation first.
For classes TGraphErrors and TGraphAssymErrors the situation becomes a
little bit more complicated since the error bars have to be changed.

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.

- Mods in TGraphAsymmErrors.h
The internal dynamic arrays fEXlow,fEXhigh,fEYlow,fEYhigh have their type changed from Float_t to Double_t
class VersionID changed from 1 to 2.
New constructor:
TGraphAsymmErrors(Int_t n);
The arguments of the other constructors are now mandatory:
TGraphAsymmErrors(Int_t n, Float_t *x, Float_t *y, Float_t *exl=0, Float_t *exh=0, Float_t *eyl=0, Float_t *eyh=0);
TGraphAsymmErrors(Int_t n, Double_t *x, Double_t *y, Double_t *exl=0, Double_t *exh=0, Double_t *eyl=0, Double_t *eyh=0);
The following functions have their arguments or return type
changed from Float_t to Double_t:
virtual void ComputeRange(Double_t &xmin, Double_t &ymin, Double_t &xmax, Double_t &ymax);
Double_t GetErrorX(Int_t bin);
Double_t GetErrorY(Int_t bin);
Double_t *GetEXlow() {return fEXlow;}
Double_t *GetEXhigh() {return fEXhigh;}
Double_t *GetEYlow() {return fEYlow;}
Double_t *GetEYhigh() {return fEYhigh;}
virtual void SetPoint(Int_t i, Double_t x, Double_t y);
virtual void SetPointError(Int_t i, Double_t exl, Double_t exh, Double_t eyl, Double_t eyh);
- Mods in TGraphAsymmErrors.cxx. See changes in TGraphAsymmErrors.h.
TGraphAsymmErrors::Streamer modified to read old objects written in single precision.
