8 * Class name: Issue
9 * Goal: Saving an attribute of the negotiation along with its value,
10 * weight, utility, effect of time (all strings) and whether the attribute was
11 * agreed upon (a boolen). We also save a 2 more strings: a list of
12 * all possible values (seperated by spaces) and a list of all
13 * possible utilities (seperated by spaces). Both those lists are read
14 * from the utility file.
15 * When the server gets an accept message from the client, it checks
16 * all the agreed attributes and their values. Then, we find the
17 * position of the agreed value in the values list, and find the
18 * corresponding utility value in the same position in the utilities
19 * list. We save the corresponding utility in the issue's utility field.
