Control.Monad.Bayes.Integrator

This is adapted from https://jtobin.io/giry-monad-implementation but brought into the monad-bayes framework (i.e. Integrator is an instance of MonadMeasure) It's largely for debugging other inference methods and didactic use, because brute force integration of measures is only practical for small programs
