#' \code{summary} method for class \code{ecoNP}.
#' 
#' 
#' @aliases print.summary.ecoNP
#' @param x An object of class \code{summary.ecoNP}.
#' @param digits the number of significant digits to use when printing.
#' @param ... further arguments passed to or from other methods.
#' @return \code{summary.ecoNP} yields an object of class \code{summary.ecoNP}
#' containing the following elements: 
#' \item{call}{The call from \code{ecoNP}.}
#' \item{n.obs}{The number of units.} 
#' \item{n.draws}{The number of Monte Carlo samples.} 
#' \item{agg.table}{Aggregate posterior estimates of the marginal
#' means of \eqn{W_1} and \eqn{W_2} using \eqn{X} and \eqn{N} as weights.} If
#' \code{param = TRUE}, the following elements are also included:
#' \item{param.table}{Posterior estimates of model parameters: population mean
#' estimates of \eqn{W_1} and \eqn{W_2}. If \code{subset} is specified, only a
#' subset of the population parameters are included.} If \code{unit = TRUE},
#' the following elements are also included: 
#' \item{W1.table}{Unit-level posterior estimates for \eqn{W_1}.} 
#' \item{W2.table}{Unit-level posterior estimates for \eqn{W_2}.}
