#' abmodel-class
#'
#' \strong{abmodel} is an S4 class that contains the ensemble model.
#' Besides the base learning algorithms--\code{base_models} --
#' \strong{abmodel} class contains information about the
#' dynamic selection method to apply in new data.
#'
#' @slot base_models a list of decision tree classifiers
#'
#' @slot form formula
#' @slot data dataset used to train \code{base_models}
#'
#' @slot dynamic_selection the dynamic selection/combination method
#' to use to aggregate predictions. If \code{none}, majority vote is used.
#'
#' @seealso \code{\link{autoBagging}} function for the
#' method of automatic predicting of the best workflows.
