Calculate the p-value on a given neutrino model based on the binned Poisson likelihood.
The PoissonBinnedLikelihoodCalculator :
PoissonBinnedLikelihoodCalculator calBG (for the atmospheric background)
PoissonBinnedLikelihoodCalculator calSinal (for the neutrino model such as GZK to be tested)
PoissonBinnedLikelihoodCalculator calNuisanceSingal (for the nuisance signal - like E^-2 against the GZK test)
are generated by the correponding binned data from the files and then executes the methods
provied by ModelTestByPoissonBinnedLikelihoodFactory.
The likeliihood ratio type 2
2 alternative hypothesis(bg + model signal with floated normalization)/null hypothesis(bg + model signal (+ nuisance))
is used for the test-statstic
