This implements the "LiquidCrystal" library for the i2c_lcd boards that BitWizard produces.
See: http://www.arduino.cc/en/Hacking/Libraries for info on where to put this library directory. It is ~/sketchbook/libraries under Linux.
Not all functions are implemented yet. Things like blinking cursors and not blanking are not yet implemented.
Neither are extra features like adjusting the contrast and the backlight intensity.
To use:
change #include <LiquidCrystal.h> into #include <i2c_lcd.h>
and change LiquidCrystal lcd (......); into LiquidCrystal lcd;
