/**
 * codatech-rfid.h provides an API for the Codatex RFID sensor.  This program
 * demonstrates how to use that API to use the sensor in single shotted mode.
 *
 * Changelog:
 * - 0.1: Initial release
 * - 0.2: Removed common.h include
 *
 * Credits:
 * - Big thanks to Sylvain Cacheux for writing the initial drivers.
 *
 * License: You may use this code as you wish, provided you give credit where it's due.
 *
 * THIS CODE WILL ONLY WORK WITH ROBOTC VERSION 3.59 AND HIGHER.
