Title: Use pin-specific SharedPreferences instead of Default SharedPrefs

This will make it so clearing out the SharedPreferences does not wipe out ALL shared preferences that may be used by the application already (since this is a library project). Alternately the clear() method could be modified to simply nullify the keys, but it is probably safer as a library to completely isolate your prefs.
