#' @title Consumer's Risk for Multi-state RDT with Multiple Periods and Criteria for Separate Periods
#' @description Define the consumer risk function hich gets the probability of passing the test when the lower level reliability requirements are not satisfied for any cumulative periods.
#' The maximum allowable failures for each separate period need to be satisfied to pass the test (for Multi-state RDT, Multiple Periods, Scenario I)
#' @param n RDT sample size
#' @param cvec Maximum allowable failures for each separate period
#' @param pivec Failure probability for each seperate period
#' @param Rvec Lower level reliability requirements for each cumulative period from the begining of the test.
#' @return Probability for consumer's risk
#' @examples
#' pi <- pi_MCSim_dirichlet(M = 1000, seed = 10, par = c(1, 1, 1))
#' MPSep_consumerrisk(n = 10, cvec = c(1, 1), pi = pi, Rvec = c(0.8, 0.7))
