/** 
 * NetConnector is a simple subclass of NetConnection with a 
 * predefined onStatus handler and is listenable to notify 
 * listeners when the connection status changes. Listeners
 * must implement an onConnect(nc, info) method.
 * This class relies on the existance of the
 * hashCodeManager object and the Listenable class.
 * Unlike the NetConnection object this class expects a URI
 * to be passed to the constructor function. In some cases 
 * objects such as the RemoteObjectManager may have to be
 * notified of a connection before other objects.
 * The notify method sorts by hash code before notifing listeners.
 * Since the hashCodeManager provides numeric strings the earlier
 * an object get a hash code the more likely it will be a lower
 * number.
