inputs/TEAM/VL, VT: Split concatenated flat files apart into separate parts each time a header is duplicated, so that the header would be autoremoved by cat_csv. Changed modified BIEN2 flat file headers back to original headers (the duplicated headers) so the headers of all part files would match up. (This is required for cat_csv header autoremoval to work properly.) This results in changes to the input column names in */map.csv.
