#' Display basic summary information in a tabular form.
#'
#' \code{get.predinfo()} has been deprecated. Information given
#' is now provided in the basic print of a
#' \code{\link{predict.slmfit}()} object. Creates a list of tables that shows the prediction, standard error, and
#' confidence interval for the prediction, as well as some summary information
#' about the sample.
#'
#' @param x the output of the \code{\link{predict.slmfit}()} function, of class \code{predict.slmfit}
#' @param conf_level is the confidence level for a normal-based
#' confidence interval (default = 0.90).
#' @return a list of three tables, including \itemize{
#' \item \code{simptab}, which contains the prediction and its standard error,
#' \item \code{confbounds}, which contains a confidence interval for the prediction, and
#' \item \code{outptmat}, a table of sampling information, including the number of sites sampled, the total number of sites, the total observed response, and the
#' observed average density (equal to the average response if all site areas are
#' equal).
