--Finished replacing broken components (GPS, Wifi, USB hub, Teensy, DC-DC converter).  All appear to be working normally.
--Started working on run-gps.cpp (started from clone of run-imu.cpp)
--Have first draft of run-gps.cpp running, sending raw NMEA sentences (of the GPRMC and GPGGA types) back to the imu-log.txt file on seykhl.  Also need to modify rover_server_log to allow multiple connections to the log_imu_sockfd port for logging (need 3: IMU, GPS, encoders).
