drives LiquidCrystal Displays (LCD) that are connected to Firmata (via I2C).

Supported are Displays that use a PCF8574T as I2C Bridge (as found on eBay when searching for

'LCD' and 'I2C'). Tested is the 1602 type (16 characters, 2 Lines), the 2004 type (and other cheap chinise-made

I2C-LCDs for Arduino) ship with the same library, so they should work as well.
