This class implements the Hypothesis test calculation using an hybrid (frequentist/bayesian) procedure.

A frequentist sampling of the test statistic distribution is obtained but with mariginalization of the nuisance parameters. The toys are generated by sampling the nuisance parameters according to their prior distribution.

The use of the of ToyMCSampler as the TestStatSampler is assumed.
