ToyMCSampler is an implementation of the TestStatSampler interface.

It generates Toy Monte Carlo for a given parameter point and evaluates a TestStatistic.

For parallel runs, ToyMCSampler can be given an instance of ProofConfig and then run in parallel using proof or proof-lite. Internally, it uses ToyMCStudy with the RooStudyManager.
