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

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.
