/**
 * HTCS-driver.h provides an API for the HiTechnic EOPD Sensor.  This program
 * demonstrates how to use that API.
 *
 * Changelog:
 * - 0.1: Initial release
 * - 0.2: Nicer intro
 * - 0.3: More comments
 * - 0.4: Removed common.h from includes
 *
 * Credits:
 * - Big thanks to HiTechnic for providing me with the hardware necessary to write and test this.
 *
 * 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.
