#' Consumer Welfare: Inclusive Value Rand. Coef.
#'
#' Given a pair of functions for drawing from the distribution of the econometric errors,
#' draw from the distribution, run the Zeta Fixed Point to re-compute prices and profits for each draw,
#' and find the inclusive value (which is the consumer's expected welfare).
#'
#' @param mc_error_fun function for drawing from the marginal cost errors
#' @param struct_error_fun function for drawing from the utility errors
#' @param draws the number of draws to take
#' @param tol when should the zeta fixed point converge
#'
#' @return numeric consumer welfare
#' @export

#' @examples #NA
