/**
* Represents a currency. Currencies are identified by their ISO 4217 currency
* codes. Visit the <a href="http://www.bsi-global.com/">
* BSi web site</a> for more information, including a table of
* currency codes.
* <p>
* The class is designed so that there's never more than one
* <code>Currency</code> instance for any given currency. Therefore, there's
* no public constructor. You obtain a <code>Currency</code> instance using
* the <code>getInstance</code> methods.
* <p>
* Users can supersede the Java runtime currency data by creating a properties
* file named <code><JAVA_HOME>/lib/currency.properties</code>. The contents
* of the properties file are key/value pairs of the ISO 3166 country codes
* and the ISO 4217 currency data respectively. The value part consists of
* three ISO 4217 values of a currency, i.e., an alphabetic code, a numeric
* code, and a minor unit. Those three ISO 4217 values are separated by commas.
* The lines which start with '#'s are considered comment lines. For example,
* <p>
* <code>
* #Sample currency properties<br>
* JP=JPZ,999,0
* </code>
* <p>
* will supersede the currency data for Japan.
*
* @since 1.4
