//
// 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.
