CLASS 
CtdLog

DESCRIPTION
Logs CTD data through the DataLogWriter interface.

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

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

  [...other stuff...]

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

</pre>
