/*
TODO: Препроцессинг и сохранение приказов

Когда приказ (последовательность команд) поступает на сервер, игрок получает
уведомление о том, что его команды приняты к производству. Каждая команда из
приказа проверяется на корректность и получает отдельное подтверждение. Игрок
может послать любое количество приказов по своему усмотрению, однако, каждый
новый приказ отменяет предыдущий. Таким образом, можно исправить неверно
составленный приказ, но при этом необходимо повторить те команды, которые
были отданы верно. К счастью, программа-клиент помогает игроку не запутаться
в этом процессе и берёт на себя контроль за целостностью приказов.
