  LiquidCrystal Library - setCursor
 
 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 prints to all the positions of the LCD using the
 setCursor(0 method:
  
 The circuit:
 =================================

// include the library code:

// your LCD using them:
const int numRows = 2;
const int numCols = 16;

// initialize the library with the numbers of the interface pins
