Update Note 2014/10/31

- integrated OBD-II parser into BluetoothChat class
- the parser should now parse the correct data required in the TripData
class
- implemented .csv file writer DataWriter.java class that writes out
parsed data
- updated UserStatActivity.java class so the parsing code now matches
the log created by Social Drive
