#' @title Modify the opacity of the expanded representation of a 'leaflet' map
#'
#' @description Modify the opacity of the expanded representation of a 'leaflet' map for
#' proportional circles and chroropleth.
#'
#' @details Seule la representation elargie est concernee par la modification de
#' l'opacite. La representation principale reste 100 pour cent opaque.
#'
#' @usage set_opacite_elargi(map, opacite = 0.6, map_leaflet = NULL)
#'
#' @param map objet leaflet.
#' @param opacite valeur numerique (numeric). Chiffre entre 0 (transparent) et
#' 1 (opaque). Par defaut a 0.6 (60 pour cent d'opacite ou 40 pour cent de
#' transparence).
#' @param map_leaflet objet leaflet. Pour l'integration des fonctions leaflet
#' dans les applications shiny (cf vignette). Par defaut a NULL.
#'
#' @return Retourne un objet leaflet.
