Currency directory

The outlet's main currency reaches a template through four different properties of the ICafeSetup model, and they are not interchangeable.

Only two are typed by hand, and both are text fields of the currency settings card:

• CurrencyShortName — Administration → Store Settings → Currency settings → In reports: → basic unit. No stock document prints it, and an empty string here is normal.
• ShortCurrencyName — Currency settings → Graphics interface: → basic unit. This is the mark a sum is labelled with; the back office refuses to save it empty.

The other two cannot be configured:

• CurrencyIsoName — the three-letter ISO code. The currency is picked from a closed list, and the same code decides how many decimal places a conversion keeps.
• CurrencyName — the name in the form exactly one phrase needs, "ALL SUMS IN …", upper-cased. The till takes it from a built-in directory by the currency code, and the form follows the terminal language. With a code the directory does not know, the property returns an empty string.

The whole built-in directory follows: the currency code and the form CurrencyName returns.
