	 *  There are 5 events a restaurant can send to the Server which has to be communicated to the Client:
	 *  	ORDER_RECEIVED("orderReceived"),
	 * 		ORDER_ACCEPTED("orderAccepted"),
	 *		BILL_GENERATED("generateBill"),
	 * 		ORDER_COMPLETED("orderCompleted"),
	 * 		MODIFY_ORDER("modifyOrder");
	 * 
	 * The Restaurant will return the following information:
	 * 1) Client ID
	 * 2) Table ID
	 * 3) RestaurantId
	 * 4) Order ID
	 * 
	 * Order Id is the Channel to publish the notification to the client.
	 * 
	 * Eg URL:
	 * ORDER_RECEIVED
	 *		restOrder?action=orderReceived&orderId=jjoJuiPitd
	 * ORDER_ACCEPTED
	 * 		restOrder?action=orderAccepted&orderId=Oid
	 * BILL_GENERATED
	 * 		restOrder?action=generateBill&orderId=Oid
	 * ORDER_COMPLETED
	 * 		restOrder?action=orderCompleted&orderId=Oid
	 * MODIFY_ORDER
	 * 		restOrder?action=modifyOrder&orderId=Oid
