/**
 * Setting various properties will change the behavior of the FlashAlert widget.  With the no properties specified,
 * the widget will display all flash data using the key as the alert class (success, info, warning, or danger) and
 * value as the message. If a message is provided, no flash data is used and only that message is used (you will also
 * need to specify the type or else the default "info" will be used). Finally, if registerAsDefaults is set to true,
 * no flash data or message will be used but the properties you specified will be used as defaults for future widgets.
 *
 * See {@link http://bootstrap-notify.remabledesigns.com/ Bootstrap Notify} for descriptions of each option and setting.
