Of course there will be documentation in time. But meanwhile:
The lib called lcd_hd44780_serial is run at you main pic and provides the standard interface. It connects via one pin (using serial software) to the "display". And "display" means in this case: an hd44780 compatible display, connected to a 16f88 with the file from project. And the one wire goes to the serial_rx pin of this 16f88. And for what flooding is concerned: you should either make sure you don't (send a limited amount of messages at a fixed interval) or (even better) use some kind of framing and when you send a message, wait for the response.
