CLASS 
PSA916Log

DESCRIPTION
Logs PSA916 data through the DataLogWriter interface.

To use this class, instantiate an instance within a PSA916 object
and periodically invoke the write() method:
<pre>

  PSA916Log *log = new PSA916Log(this, DataLog::AsciiFormat);

  [...other stuff...]

  // Log the data
  log->write();

</pre>
