boost::shared_ptr< diagnostic_msgs::DiagnosticStatus > StatusItem::toStatusMsg	(	const std::string &	path,
		const bool	stale = `false`
	)		const

Prepends "path/" to name, makes item stale if "stale" true.

Helper function to convert item back to diagnostic_msgs::DiagnosticStatus pointer. Prepends path. Example: Item with name "Hokuyo" toStatusMsg("Base Path/My Path", false) gives "Base Path/My Path/Hokuyo".
