/**
 * Extending Bootstrap Select Elements to build the simple
 * currency picker Select element.

 * VTCore_Wordpress_Data_Iso Class and should be paired with
 * VTCore_Wordpress_Element_WpCurrency for the display element.
 *
 * Extra additional context :
 *
 * currency     : (array) array of currency iso code that will be
 *                      used to build the select options. if omitted
 *                      or set to false, object will build all available
 *                      currency
 *
 * display      : (string) the display mode for the options text, valid value
 *                       are symbol, name or iso_code
 *
 * include      : (boolean) include the currency object as html5 data-currency attributes
