The default units have been changed to meters/sec^2 to better represent
the Android API defaults. Small bug changes to the logger have been
implemented, including a change to to the file names to reflect the
date/time the log was taken and updates to the media scanner so the file
will appear on Android 4.3+. Logging data to a file is now performed
within its own thread to allow maximum data logging speeds... over 180Hz
is now possible.
