/**
 * The {@link Buyer} class is extended in a way that the buyer negotiators could be created by using different random utility functions among 
 * UF_CloseToQuantity, UF_LessPrice, UF_LessPriceCloseToQuantity, UF_IntensifiedLessPriceCloseToQuantity, UF_PeakedPricePeakedQuantity, 
 * UF_PeakedFlatPricePeakedFlatQuantity, UF_PeakedFlatCurvePriceGaussianQuantity, UF_BezierPriceBezierQuantity, and 
 * UF_BezierPriceGaussianQuantity, where the first function takes only quantity into account, 
 * the second function considers only price, but all the others deal with both price and quantity, receive different numbers of parameters, 
 * and consider the importance of issues (i.e., for price, quantity, etc.) as well as the importance of Chips (i.e., colors) with respect to each other. 
 * It also created buyer negotiators using either Boulware or Bargaining (based on NiceTitForTat) negotiation strategies.
