/**
 * dexterind-flex.h provides an API for the Dexter Industries dFlex Sensor.  This program
 * demonstrates how to use that API to calibrate the sensor.
 *
 * Changelog:
 * - 0.1: Initial release
 *
 * Credits:
 * - Big thanks to Dexter Industries 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.
