        Profile is a very general object describing how much a {@link Bid} is
        preferred. "is preferred" can be worked out in different ways, eg by a
        function "isBetter" that says if bid1 is preferred over bid2, or by assigning
        utility values to each bid that says how much I like that particular bid. All
        profiles should be implemented immutable

                @return a (hypothetical) bid that is the best alternative to a
                        non-agreement. Only bids that are equal or better should be
                        accepted. If a negotiation does not reach an agreement, the party
                        can get this offer somewhere else. This replaces the older notion
                        of a "reservation value" and is more general. If None, there is
                        no reservation bid and any agreement is better than no agreement.
                        This bid can be partial.
