  Unfortunatly explicit constructors cannot be added since arenot supported by CINT. One should then use in 
  Python or CINT dummy constructor + operator=.

Main changes are: 

- improve integrator interface adding template functions taking as imput any C++ callable object for evaluation 
  of the integrals
- use ROOT convention for enumeration names (start with k, like kADAPTIVE for the integration type). Change for 
  Integration types, Interpolation types (in MathMore) and Minimizer1D types. Change all classes and tests using this 
  enumeration name  
- improve RichardsonDerivator class (used by TF1::Derivative). Remove an un-needed function call
  Fix also a bug in calculation of the error returned by TF1::DerivativeError
- change interface for the function interfaced used for fitting (IParamFunction function and IParamGrad function)
  Requires now that the parameter values are passed when evaluating the function and the gradient and make the method
  operator()(double *x, double *p) const. Derived class must implement DoEvalPar (and not DoEval as before) 
  for implementing this interface. This change makes the caching of parameter not hidden and the interface is now 
  thread-safe.  In the IParamGradFunction interface remove the funcitonality for gradient of the coordinates (x) 
  since it is not needed. Define only the parameter gradient. 
- improve also the ParamFunction class used by the concrete function like Polynomial. Adapt Polynomial class to new 
  parameteric function interface
- improve Fit Result class with function to get parameter correlations after the fit and to fill any generic matrix 
with covariance or correlation result. 
- add method also in the minimizer interface to get correlation values 
- add strategy in the minimizer control parameters
- increase timing of stressMathCore and stressMathMore

- use std::string for parameter name and remove un-necessary limitation on the length of parameter name
   maintan the Name() method returning a char * (for backward compatibility) and add a new method GetName() returning 
   a reference to a std::string
- add also a method in MInuit2Minimizer to get correlation coefficient between parameter i and j  and a method to get 
  the global Correlation coefficient of parameter i
- add new complex tests of fitting used for parallelization studies 
- compile in ROOT also the tests in MnSim and MnTutorial

strangely enough Wndows does not support %p, use good old 0x%lx.

using %p as format flag instead of 0x%x allows pointers to be passed
on 64bits, too.

a fix for TFFTRealComplex::GetPointComplex(Int_t *,...) function, for the case of transforms of more than 2 dimensions. The real index in the internal 1-d flat array is now computed correctly, taking into account that only ~half of entries are stored because of Hermitian symmetry. And thanks to Christophe Yeche for pointing it out.

The concrete implementation of the class is in TCint.
The new functions are essentially interfaces to the existing CINT C++ classes
like G__ClassInfo, G__CallFunc, G__DataMemberInfo, G__MethodInfo, G__TypeInfo
and G__TypedefInfo. Most of these functions will call the Reflex interface
once the CINT/Reflex interface will be available later this year.
All direct calls to CINT are replaced by calls like gCint->ClassInfo_xxx where gCint
points to the TCint implementation.
The existing calls to TCint via gInterpreter are kept because on Windows
gInterpreter does not call directly TCint, but instead call TWin32InterpreterProxy
that in turns call TCint.
On Linux and Mac, gInterpreter and gCint are equivalent.

Once the transformation using gCint will be completed, it will be possible
to specify at startup time which version of CINT (CINT or CINT7) by loading
dynamically TCint or TCint7.--This line, and those below, will be ignored--

Use as the name of the template argument of the templated member function a symbol that is _not_ also the name of a function in order to avoid a fatal confusion in order compilers (gcc 3.3)

- improve chi2test to consider the case of weighted histograms (options UW or WW) and the histograms 
  have zero bin errors. 
 (For example in case an histogram is compared to a function represented as an histogram with zero errors)

- suppress in unuran tests info message produced by  chi2 test

call TMath::LnGamma instead, otherwise we can explode memory
when fitting histograms with big bin contents with the Likelihood option.

- improve chi2 test for the treatment of empty bins. Fix cases with option WW or UW and both histograms had empty bins.
  For UU and only one histogram has an empty bin do not decrease ndf as suggested by I. Reid.
