#' Piirkonnale andmebaasides olevate punktide lisamine
#'
#' Etteantud piirkonna geomeetrilise piirjoone ('piir') ja selle joone piirikasti ('bb') järele leitakse nende aladega kaetud polügoonid. Andmed salvestatakse postgis andmebaasi.
#'
#' @param obj str Objekti nimi. Edaspidi on oluline ainult see nimi. Piirkonna geomeetrilist joont ei ole vaja lisada.
#' @param conf A list() of configuration variables. Default values \code{\link[ruut]{get_config}}.
#' @return Uute andmebaasi kihtide 'piir_...' ja 'bb_...' loomine.
