Example: get_dutch_banks("username", "password")
Purpose: Returns a list of Dutch banks and their BICs. Dutch domestic bank account numbers do not contain reliable information about the bank in which they are held. While there is a bank code (of variable length) embedded in Dutch account numbers, thanks to the possibilty that bank clients can keep their account number when switching banks, there exist accounts where the embedded bank code does not match the bank holding the account. When calculating a Dutch IBAN, you need to pass an account number and a BIC to the function calculate_iban; the BIC can be picked from the list which is returned by the function get_dutch_banks.
