/** @file mica2-light-temp.h
 * @brief Integrated light and temp sensor driver for the mica2.
 * 
 * This driver registers with the dev layer as two differnt devices, but they are 
 * intertwined in hardware so we implement it in one file.
 * @author Brian Shucker
 * @author Based on light.c and temp.c by Charles Gruenwald III
