 // probability can be a single object representing a vector with a Dirlichet prior (see below) or a vector of calibrated values
 //add bernoulli instruction (similar to markov-switching for independent draws) and new options to create bernoulli process
 // I don' know if probabilities would be a better name than probability (vector  being implicit)
