Construct an IBAN from a country code and the domestic account parts, computing the ISO 7064 mod-97-10 check digits. Takes either a single BBAN string or named parts (bank code, branch code, account number); digit fields are left-padded with zeros to the country's registered widths. Returns the IBAN in electronic and print formats with its bank, branch and account parts. Covers the 89 SWIFT registry countries. Named parts work only where they span the whole BBAN; otherwise pass the BBAN.
