Defines functions pns_design

Documented in pns_design

#' Create PNS survey object with its sample design
#' @description This function creates PNS survey object with its sample design for analysis using \code{survey} package functions.
#' @import dplyr httr magrittr projmgr RCurl readr readxl survey tibble timeDate utils
#' @param data_pns A tibble of PNS microdata read with \code{read_pns} function.
#' @return An object of class \code{survey.design} or \code{svyrep.design} with the data from PNS and its sample design.
#' @note For more information, visit the survey official website <\url{https://www.ibge.gov.br/estatisticas/sociais/saude/9160-pesquisa-nacional-de-saude.html?=&t=o-que-e}> and consult the other functions of this package, described below.
