Adding logging script

+#HOW TO USE THIS SCRIPT:
+# run "python positionGaugeServer_logging.py ARDUINO_HOSTNAME_OR_IP | tee LOGFILE.TXT"
+# This will connect to the given arduino,
+# and continiously write a file "LOGFILE.TXT" (pick a sensible name!).
+# Due to the use of "tee" it will also show the contents of this file while it is running.
