- apply a fix in copy ctor of MinimizerOptions (did not copy name) 
 - make some methods in Minimizer const

- add support to the Brent classes to perform a grid search in log bins

- improve 1D root finder and minimization classes

  - return a bool in method RootFinder::Solve and IMinimizer1D::Minimize
   to be consistent with the other numerical algo. classes
   Classes in MathCore were also returning the wrong values (status=1 instead of zero)

  - add Status() method to check the validity of the cached values

  - change default tolerance to 10-8 (abs) and 10^-10 (values which were used as default in the Mathcore Brent)

  - return a bool also in SetFunction

- Mathcore Brent classes: 

   - pass tolerances and max iterations to the Brent methods. So do not use anymore the hard coded values
   - add possibility also to pass Npx (number of points to use in the grid for the bracketing search) and max number 
     of iterations (before was hard coded to 10)
    

This changes uses suggestion reported by https://savannah.cern.ch/bugs/index.php?61242

Syncronize with the Math develoment branch: 
 
- merge classes from math (TMath, TComplex and TRandom) in libMathCore
- change various functions of TMath (work from David ):
	- make a single template functions for all the various types (like Sort or Binart Search) 
        - use std implementations for Sort, BinarySearch, LocMin
        - use mathcore special functions for Gamma and Beta functions 

- remove genvector from mathcore
- add classes for integration, derivation and root findings using the algorithms of TF1
-  use the plug-in manager to instantiates different implementations of the same classes in MathMore

Interface IRootFinderMethod created. GSLRootFinder, GSLRootFinderDeriv and BrentRootFinder are redesigned so that they derive from it. Also RootFinder class changed from templated class Interfaced classes (with IRootFinderMethod). GSL_BISECTION, GSL_NEWTON and GSL_STEFFENSON methods fail to be loaded with the plugin manager
