 - add new AsymptoticCalculator and its support in HypoTestInverter
 - add utility function to make the nuisance pdf
   + various small improvements

- add a new function TMath::Power(double, int) impelmented using std::pow(double,int) since it is 100% faster

- fix for new Power function some code in TMVA 

- Fix in TMath implementation of IsNaN for the latest C++ compiler when used together with cmath

Shift the verbosity level passed to TFileMerger up down by one to allow for finer grain control in hadd.
Now:

$ hadd -v 2 -f output.root input1.root input2.root

   hadd -f output.root -T input1.root input2.root

to properly recognize the 'output.root' to be the output rather than input1.root
(i.e. previously the first argument after all the -* option was assumed to be
the output even if it was specified before hand).
