CLASS 
GpsLog

DESCRIPTION
Logs GPS data through the DataLogWriter interface. Constructor
takes an instance of an object that implements the Gps interface.

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

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

  [...other stuff...]

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

</pre>
