 * An offer has two parts: (1) a bundle or null, (2) a message code: `bid', `accept', `end'.
 * When the code is 'bid', the first part is checked; for the two latter codes, the first part of the offer is null.
 * In other words, message `bid' means that offer contains a bundle which is proposed, `accept' means offer contains no bundle to propose, 
 * but an agreement with the deal (the received offer), and `end' again means that nothing to propose, and quitting the negotiation.
