	 * Handles a message sent on the EditBus.
	 *
	 * This method must specify the type of responses the plugin will have
	 * for various subclasses of the {@link EBMessage} class. Typically
	 * this is done with one or more if blocks that test
	 * whether the message is an instance of a derived message class in
	 * which the component has an interest. For example:
	 *
	 * 
 if(msg instanceof BufferUpdate) {
         *     // a buffer's state has changed!
         * }
         * else if(msg instanceof ViewUpdate) {
         *     // a view's state has changed!
         * }
         * // ... and so on
* * @param message The message */ void handleMessage(EBMessage message); }
