In Bolstad: Functions for Elementary Bayesian Inference

#' Print method for objects of class \code{sscsample}
#' 
#' This function provides a print summary method for the output of
#' \code{sscsample}. The \code{sscsample} produces a large number of samples
#' from a fixed population using either simple random, stratified, or cluster
#' sampling. This function provides the means of each sample plus the number of
#' observations from each ethnicity stratum in the sample.
#' 
#' 
#' @param x an object of class \code{sscsamp} produced by \code{sscsample}
#' @param \dots any other arguments that are to be passed to \code{cat}
