 * Lightweight macro implementation of Arduino style pin numbering
 * for AVR microprocessors. Because only thing I want to use from
 * Arduino libraries is the pin numbering scheme.
 * 
 * This file taken 99% from the excellent ArduinoLite project by 
 * Shikai Chen <csk@live.com>. Some minor changes to suite my personal 
 * coding taste.
