#' get_technology
#'
#' get_technology returns a data frame of accountability technology data from the
#' Nevada Report Card (NRC) API given a numeric vector of NRC organization ids.
#'
#' All of the data that can be pulled by this function is already available in a data frame
#' `nrc_technology` that comes with the nrc package; View(nrc_technology). This function was
#' used to create that data frame.
#'
#' @param org_ids A numeric vector of NRC organization ids. You can look them up for a school or
#' district by using get_org_id(name). These can be viewed by looking at the
#' nrc_orgs data frame that comes with the nrc package.
#' @param spring_years a numeric vector of spring school years.
#' For example, 2016 would be submitted for the 2015-2016 school year and
#' 2015:2016 would be provided to get both the 2014-2015 and 2015-2016 school years.
#'
#' @return returns a data frame of accountability fiscal data.
