/**
 * Returns a <select> tag populated with all the currencies in the world (or almost).
 *
 * The select_currency_tag builds off the traditional select_tag function, and is conveniently populated with 
 * all the currencies in the world (sorted alphabetically). Each option in the list has a three character 
 * currency code for its value and the currency's name as its display title.  The currency data is 
 * retrieved via the sfCultureInfo class, which stores a wide variety of i18n and i10n settings for various 
 * countries and cultures throughout the world. Here's an example of an <option> tag generated by the select_currency_tag:
 *
 * <samp>
 *  <option value="EUR">Euro</option>
 * </samp>
 *
 * <b>Examples:</b>
 * <code>
 *  echo select_currency_tag('currency', 'EUR');
 * </code>
 * <code>
 *  echo select_currency_tag('currency', 'EUR', array('currencies' => array('EUR', 'USD'), 'display' => 'symbol'));
 * </code>
 *
 * @param  string $name      field name 
 * @param  string $selected  selected field value (threecharacter currency code)
 * @param  array  $options   additional HTML compliant <select> tag parameters
 *
 * @return string <select> tag populated with all the currencies in the world.
 * @see select_tag, options_for_select, sfCultureInfo
