Common base class for the Hypothesis Test Calculators.

It is not designed to use directly but via its derived classes

Same purpose as HybridCalculatorOriginal, but different implementation.

This is the "generic" version that works with any TestStatSampler. The HybridCalculator derives from this class but explicitly uses the ToyMCSampler as its TestStatSampler.

inherited methods from HypoTestCalculator interface

several possibilities: no prior nuisance given and no nuisance parameters: ok no prior nuisance given but nuisance parameters: error prior nuisance given for some nuisance parameters:

nuisance parameters are constant, so they don't float in test statistic
nuisance parameters are floating, so they do float in test statistic
