#' @title Show fitted labels for the GenSVM model
#'
#' @description This function shows the fitted class labels of training data 
#' using a fitted GenSVM model.
#'
#' @param object Fitted \code{gensvm} object
#' @param \dots further arguments are passed to predict
#'
#' @return a vector of class labels, with the same type as the original class 
#' labels.
