	* When this object is instantiated, it creates a wrapper object *
	* for the Flash movie who's ID is specified, enabling a rich    *
	* set of controls to be used from JavaScript. In addition, it   *
	* also creates the FSCommand handling function which allows     *
	* Flash to call using FSCommand any JS function.                *
	*                                                               *
	* NOTE: Due to Flash Player security settings, this needs to    *
	* work off a web server, and not off a local or network disk.	*
