+// the corresponding Listings. A few notes:
+// - This script does not delete or modify any existing listings.
+// - If one listing fails to be uploaded, the script will still attempt all the rest. At the end,
+//   it will report how many failed (with error messages) and how many succeeded.
+// - Each line in the CSV file is assumed to correspond to a distinct listing.
+// - This script assumes particular heading names in the input CSV file (see listingFields["..."]
