 based on arduino LiquidCrystal Library - TextDirection
 
 Demonstrates the use a 16x2 LCD display.  The LiquidCrystal
 library works with all LCD displays that are compatible with the 
 Hitachi HD44780 driver. There are many of them out there, and you
 can usually tell them by the 16-pin interface.
 
 This sketch demonstrates how to use leftToRight() and rightToLeft()
 to move the cursor.
