#' Get reference data from Go.Data
#'
#' A function to retreive a list of all reference
#' data and their attributes, across all outbreaks
#' on the instance (since this is a system-level API
#' endpoint). This function relies on the
#' `\reference-data` API endpoint.
#'
#' @param url Insert the base URL for your instance of Go.Data here. Don't
#' forget the forward slash "/" at end!
#' @param username The email address for your Go.Data login.
#' @param password The password for your Go.Data login
#'
#' @return
#' Returns data frame of reference data associated with Go.Data instance.
#' @export
#' @examples

#' url <- "https://MyGoDataServer.com/"
#' username <- "myemail@email.com"
#' password <- "mypassword"

#' reference_data <- get_reference_data(
#'   url = url,
