#' Create a tab-delimited file with MDVs and a csv file with FC or \%labeled for INCA
#' @author Daniel Braas
#' @param iso_data The input which contains the isotopologue data
#' @param QE A set of metabolites to be returned
#' @param label_data Either percent labeled or fractional contribution
#' @return Two csv files with a) isotopologue information for INCA and b) a data frame
