#' Eurostat Geonomenclature to FAO area codes mapping
#'
#' Extracted from CountryCode table of FRA_2012.mdb located in

#' Idea suggested by Claudia
#'
#' @format A data frame: code (integer) Geonom code,
#' faostat (integer) - FAO area code,
#' active (integer) - FAO area code to use. For example, French Guiana
#' goes to France. So we don't need to aggregate later (probably). Abandoned codes,
