##Trader Events

Trader registers ziAgent.Prototype.sendBidsAndAsks as the first responder to the Agent Wake event.

##Trader subclasses (e.g. ZIAgent, etc.)

inherit Agent and Trader events and behavior

##Pool Events

Pool is not an EventEmitter of its own.

Instead, several Pool methods call methods on all agents in the Pool, triggering related Agent events.
