Quick Start
------------
1.offline
    1) fingerprints calibration.
        a) ./tool/bt-dev-con && xgps &
        b) ./run -n <start_spid> -r <repeat_times>
        c) ./offline.py -c dat/<time-spid>.rmp
        d) ./offline.py -u 1
    2) Dumbtest for stability.
        ./run -d
    3) Compile all *.py to *.pyc.
        ./run -m

2.online
    1) Pure fingerprinting.
    sudo ./online.py -v
    2) Accuracy evaluation(GPS available).
    sudo ./test.py -v
