There are two arguments, the path to the CSV for the current analysis year and the path to the CSV for the previous analysis year. For more complete testing in check_arguments(), we could compare the years in the file names for both CSVs and make sure they are in the correct order (current > previous). If they are in the wrong order, the comparison is going to be backwards.
