update notes 2014, Nov 10th:

- OBDII-reader now reads data for Fuel Economy
- modified all classes that has a .csv reading function to read the .csv
our Social Drive outputs
- modified SettingActivity so that it now supports multi-preference by
using fragments (the code is no longer shown as deprecated)
- debugged FB integration from the old source codes so that it actually
leads to the FB Social Drive page instead of blank and having FB giving
error
- changed so that Social Drive now shows login screen when entering the
app instead of showing interface activity
