Provides some functions for a nodejs-raspi-lcd arrangment. By now it works with a 20x4 LCD compatible with the Hitachi HD44780 LCD controller.

The code below lib/utils.js is a rewrite of the python code; THX to Matt Hawkins

For setting the raspi pins high and low I tested some gpio modules I found on

The one I use is rpio by jperkin. THX to him too. Infrastructure for configuring other lcd-types will be provided (if needed; open a issue).
