/**
 * This main class showcases the fundamental concepts in the Bargaining Chips game.
 * 
 * Bargaining Chips is played by a buyer who seeks to acquire a number of chips for a good price. 
 * For example, the wish list of the buyer may consist of 2 red chips and 1 blue chip. 
 * Chips represents arbitrary indivisible items, such as products or tasks and are differentiated 
 * from others by a unique color.
 * 
 * Bargaining Chips is played using an asynchronous offer protocol for each bilateral negotiation thread. 
 * Multiple deals in simultaneous threads of one-to-many negotiation need to be coordinated; therefore, 
 * the buyer is equipped with two modules, one coordinator and multiple negotiators one per each thread.
 * 
 * Each of the individual negotiations is itself a bilateral negotiation over multiple items and multiple 
 * issues, i.e. a multi-issue multi-item thread. As each thread could reach a deal, the whole negotiation 
 * could reach multiple deals. 
 *  
 * Negotiating in this setting needs some coordination efforts to synchronize threads according to the 
 * progress of each individual negotiation as well as the multiple deals compared with the party's preference.
 *   
 * Bargaining Chips is a testbed for evaluating agents in such settings.
