#' @title sumObj Class
#' @description Internal function.
#' It defines a \code{sumObj} object, storing information on the closed testing procedure on a set of interest.
#' @usage sumObj(total, size, alpha, TD, maxTD, iterations)
#' @param total total number of variables.
#' @param size size of the set of interest.
#' @param alpha significance level.
#' @param TD lower (1-\code{alpha})-confidence bound for the number of true discoveries in the set.
#' @param maxTD maximum value of \code{TD} that could be found under convergence of the algorithm.
#' @param iterations number of iterations of the algorithm.
#' @return \code{sumObj} returns an object of class \code{sumObj}, containing
#' \code{total}, \code{size}, \code{alpha}, \code{TD}, \code{maxTD} and \code{iterations}.
