- cleanup header IParamFunctionfwd and IFunctionfwd
- simplify Chi2FCN class to store just base parametric funciton pointer (like is done in other FCN classes_
This requires some changes in TLinearMinimizer
This semplification should fix the bug https://savannah.cern.ch/bugs/?84867

From Matthew Strait:
This patch fixes the spelling of "function" in the root source code
and documentation, which is misspelled (sometimes as part of larger
"function"-based words) at least 152 times:
* "funciton" 48 times
* "funcion" 36 times
* "funtion" 23 times
* "fucntion" 17 times
* "functionn" 6 times
* "fuction" 6 times
* "fuunction" 4 times
* "functioin" 3 times
* "fonction" 3 times
* "funstion" twice
* "fnuction" once
* "functiom" once
* "functio" once
* "funcition" once

- apply various small improvement to minimizer classes, in particular:
- implement NCalls() for TMinuit (thanks to Alfio) and fix cases when SetFunction has not been called
- when calling SetLimitedVariables on minimizer who do not support bounds return false instead of
setting unbound variables
- improve handling of errors for GSLMinimizer
(see http://root.cern.ch/phpBB2/viewtopic.php?t=8492 )

- remove from gROOT the linear basis function created for the linear fit
this fixes some crashes observed running a linear fit after a rest of gROOT.

import lates changes from math development branch
(from rev 26842)
The main changes are:
- add support for drawing Scan and Contour plot from FitPanel
- improve Minimizer interface by adding methods for contours and scan.
implement them using Minuit and Minuit2
Mathcore:
- improve Fitter class
mantain now after fitting a reference to the Minimizer and Objective funciton which can be used later for performing the contour and scans
- avoid a copy of FitResult class
- add new methods in Minimizer for re-setting the variable values
- fix the bin fitting using the bin function integral in combination with the gradient or with Fumili
- add dictionary for Fit method functions
Minuit2:
remove limit on number of scan points
implement scan and contour in Minuit2Minimizer
Minuit
implement scan and contour in TMinuitMinimizer
SMatrix:
Change implementation of SMatrix::Invert (and Inverse) to use the
direct Cramer method only for 2x2 (not up to 5x5)
Add SMatrix::InvertFast using Cramer method up to 5x5
(this is having now same behavior as before)
hist:
TBackCompFitter:
improve class due to change in Fitter. Use now the minimizer reference and
there is no need to re-create it
Add interface for scan and contour in TBackCompFitter
Add methods to retrieve FitResult and FitConfig
mathmore
fix a memory leak
implement changes in Minimizer
fitpanel
new dialog for the advanced drawing option with two tabs one for
drawing contour the other for drawing scan plots
fixed some meory leaks and other small problems

- fix a bug in creating TF1 as basis functions in TLinearMinimizer::SetFunction. Use names more difficult to reproduce and not f1,f2,..fN, since when a new TF1 is created the one with the same name is deleted.

import changes from math development branches for subdirectory math. List of changes in detail:
mathcore:
---------
MinimizerOptions:
new class for storing Minimizer option, with static default values that can be
changed by the user
FitConfig:
- use default values from MinimizerOption class
- rename method to create parameter settings from a function
FitUtil.cxx:
improve the derivative calculations used in the effective chi2 and in Fumili and
fix a bug for evaluation of likelihood or chi2 terms.
In EvaluatePdf() work and return the log of the pdf.
FitResult:
- improve the class by adding extra information like, num. of free parameters,
minimizer status, global correlation coefficients, information about fixed
and bound parameters.
- add method for getting fit confidence intervals
- improve print method
DataRange:
add method SetRange to distinguish from AddRange. SetRange deletes the existing
ranges.
ParamsSettings: make few methods const
FCN functions (Chi2FCN, LogLikelihoodFCN, etc..)
move some common methods and data members in base class (FitMethodFunction)
RootFinder: add template Solve() for any callable function.
mathmore:
--------
minimizer classes: fill status information
GSLNLSMinimizer: return error and covariance matrix
minuit2:
-------
Minuit2Minimizer: fill status information
DavidonErrorUpdator: check that delgam or gvg are not zero ( can happen when dg = 0)
FumiliFCNAdapter: work on the log of pdf
minuit:
-------
TLinearMinimizer: add support for robust fitting
TMinuitMinimizer: fill status information and fix a bug in filling the correlation matrix.
fumili:
------
add TFumiliMinimizer:
wrapper class for TFumili using Minimizer interface

- fix coding convention violations (mainly change name of RootFinder enumeration)
- fix warning observed on the Windows nightly (avid generating the dictionary for fit method functions for all platforms, it is not needed)
- add implementation of Minimizer interface using TMinuit and the linear fitter
- add method SetBasisFunctions in TLinearFitter class to set the linear terms
- add some optimization of wrapped functions and improve doc
