/**
 * hitechnic-gyro.h provides an API for the HiTechnic Gyroscopic Sensor.  This program
 * demonstrates how to use that API in combination with the Sensor MUX.
 *
 * Changelog:
 * - 0.1: Initial release
 * - 0.2: Now uses HTSMUX driver which has been split from common.h\n
 *        HTSMUX initialisation and scanning functions have been removed\n
 *
 * 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. 

 * Xander Soldaat (xander_at_botbench.com)
 * 20 February 2011
 * version 0.2
