A small script that converts CSV output from Sparebanken Sør to a format that YNAB can import

Usage:

python ynab.py <path-to-csv-file>

When eksporting from Sparebanken Sør, the file will usually be called transaksjoner.csv and will be placed in the Downloads folder, so the command will usually be:

python ynab.py Downloads/transaksjoner.csv

A new CSV file will be created in the same folder, with ynab- prepended to the filename.
