// extra features related to currency:
//
// 1. After specifying the currency type (american dollars, euros, etc.) it automatically
// sets parse/format options such as how many decimal places to show.
// 2. The currency mark (dollar sign, euro mark, etc.) is displayed when the field is blurred
// but erased during editing, so that the user can just enter a plain number.
// currency: [const] String
// the [ISO4217](http://en.wikipedia.org/wiki/ISO_4217) currency code, a three letter sequence like "USD"
