/**
 * This class wraps the GoController and provides an interface to a GTP based controller (front end ui).
 * GoGui is typically the controller I have used, but it could be any GTP based UI.
 *
 * This wraps my Tesujisoft go engine so that a client program can use it.
 * If you want to have the Tesujisoft go engine play on KGS use GtpKgsTesujisoftGoClient.
 *
 * Inherits the ability to connect a Go program supporting GTP to a socket from GtpServer.
