#' @title plotting hscore of each bi-cluster on bicluster dimension
#' @description funcc_show_bicluster_hscore graphically shows the hscore vs the dimension (i.e. number of rows and columns) of each bi-cluster
#' @export
#' @param fun_mat The data array (n x m x T) where each entry corresponds to the measure of one observation i, i=1,...,n, for a functional variable m, m=1,...,p, at point t, t=1,...,T
#' @param res_input An object produced by the funcc_biclust function
#' @return a figure representing the dimensions of each bi-cluster (i.e. number of rows and columns)
