/**
 * This example shows how BOA components can be made into an independent
 * negotiation party and which can handle preference uncertainty.
 * 
 * Note that this is equivalent to adding a BOA party via the GUI by selecting
 * the components and parameters. However, this method gives more control over
 * the implementation, as the agent designer can choose to override behavior
 * (such as handling preference uncertainty).
