#' Summary method for a lyapunov object
#' @name summary.lyapunov
#' @aliases summary.lyapunov
#' @description
#' summary method for class "lyapunov".
#' @usage \method{summary}{lyapunov}(object, ...)
#' @param object an object of class \code{"lyapunov"} provided by \code{\link{lyapunov.max}}, \code{\link{lyapunov.spec}} or \code{\link{lyapunov}} functions.
#' @param ... further arguments passed to or from other methods.
#' @return This function \code{summary.lyapunov} computes and returns a list of summary statistics of the results given in a \code{lyapunov} object using the components (list elements) from its argument.
#' @examples
#' ## set.seed(34)
#' ## Simulates time-series data from the Logistic map with chaos
#' ## ts <- DChaos::logistic.sim(n=1000, a=4)
#' ## show(head(ts, 5))
#'
#' ## Summary method for a lyapunov object (only 1 method)
#' ## jacobian <- DChaos::jacobian.net(data=ts, m=3:3, lag=1:1, timelapse="FIXED", h=2:10)
#' ## exponent <- DChaos::lyapunov.spec(data=jacobian, blocking="BOOT", B=100, doplot=FALSE)
#' ## summary(exponent)

#' ## Summary method for a lyapunov object (> 1 method)
