#' @title Score the FACT/GOG-Ntx-12

#' Generates all of the scores of the FACT/GOG-Ntx-12 (Version 4) from 
#' item responses.

#' @return A data frame with the following scale scores is returned:
#'
#' \itemize{
#'   \item \strong{PWB} - Physical Well-Being subscale
#'   \item \strong{SWB} - Social/Family Well-Being subscale
#'   \item \strong{EWB} - Emotional Well-Being subscale
#'   \item \strong{FWB} - Physical Well-Being subscale
#'   \item \strong{FACTG} - FACT-G Total Score (PWB+SWB+EWB+FWB)
#'   \item \strong{NtxS12} - FACT/GOG-Ntx-12 subscale
#'   \item \strong{FACTGOG_Ntx12_TOTAL} - FACT/GOG-Ntx-12 Total Score (PWB+SWB+EWB+FWB+NtxS12)
#'   \item \strong{FACTGOG_Ntx12_TOI} - FACT/GOG-Ntx-12 Trial Outcome Index (PWB+FWB+NtxS12)
#' }
#'
#' If \code{AConly = TRUE}, the only scale score returned is \strong{NtxS12}.
#'
#' If a variable was given to the \code{id} argument, then that variable will
#' also be in the returned data frame. Additional, relatively unimportant,
#' variables will be returned if \code{updateItems = TRUE} or \code{keepNvalid =
#' TRUE}.
