#' @title Make text to be shown in popups on Demographic data map
#'
#' @description
#'   Takes raw values and what percentiles they are at,
#'   and presents those as a text field to be used as the text in a popup window on a map
#' @details
#'   Note d should be a (vector? or) data.frame of exact demographic percentages from 0 to 1, not 0 to 100
#'   BUT pctile should be INTEGER 0 to 100, NOT 0 to 1!
#'   Because that is how EJSCREEN data are stored
#'   In EJSCREEN, there are three types of pctile.text fields: E (text varies), D, EJ:
#'     'pctile.text.cancer'                            "55 lifetime risk per million (91%ile)"
#'     'pctile.text.pctmin'                            "13% (30%ile)"
#'     'pctile.text.EJ.DISPARITY.cancer.eo'            "36%ile"
#' @param d raw demographic values, 0-1 (such as 0.3345 where roughly 33 percent of the local population is under age 5)
#' @param pctile required integers 0 to 100, representing the percentile(s) at which the raw value(s) fall(s).
#' @param prefix optional, default is 'pctile.text.'  This is a text string specifying the first part of the desired resulting fieldname in outputs.
#' @param basenames optional, default is colnames(d). Defines colname(s) of outputs, which are the prefix plus this.
#' @return Returns character vector or data.frame, same shape as first input parameter.
