// Following sample shows simple case of executing task asynchronously without blocking current thread.
// This is extremely handy for tasks which are not so important to block the execution of main program
// and we do depend on their execution results.
AsyncUtil.with(message).plan(MailSerializerUtil::toTempDir).async();

// It's also posible to chain async tasks plans
AsyncUtil.with(message)
            .plan(MailSerializerUtil::toTempDir)
            .plan(MailSerializerUtil::logMessage)
