Hello World

    logkit::set_default_logger(logger);

    trace!("hello, this is a trace log");
    debug!("hello, this is a debug log");
    info!(version = "0.1.0", commit = "3291cc60"; "this is a log with two string fields");
    warn!(address = "127.0.0.1", port = 3000; "this is a log with a string and a numeric field");
    error!("this is a log with a 'println' style string {}:{}", "127.0.0.1", 3000.0);
