In Bolstad: Functions for Elementary Bayesian Inference

#' Print method for objects of class \code{Bolstad}
#' 
#' This function provides a print summary method for the output of
#' \code{bayes.lm}.
#' 
#' 
#' 
#' @param x an object of class \code{Bolstad}
#' @param digits number of digits to print 
#' @param \dots any other arguments that are to be passed to \code{print.default}
#' @details if x has both class \code{Bolstad} and \code{lm} then a print method 
#' similar to \code{print.lm} is called, otherwise \code{print.default} is called
