If the following methods don’t have log data to return, they return None.

`current`()

`last`()

  The last record in the log is returned.

  This method will return None if the log is empty.

`next`()

  The current log position is advanced to the next record in the log, and that record is returned. If the cursor position was not set previously, it will return the first record in the log.

  This method will return None if the log is empty.
