 the output format before seeing any input instances, it does so here. This

 batchFinished() is called.

<DT><B>Parameters:</B><DD><CODE>instanceInfo</CODE> - an Instances object containing the input instance
 structure (any instances contained in the object are ignored - only the
 structure is required).

<DD>Signify that this batch of input to the filter is finished. If the filter
 requires all instances prior to filtering, output() may now be called
 to retrieve the filtered instances. Any subsequent instances filtered
 should be filtered based on setting obtained from the first batch
 (unless the inputFormat has been re-assigned or new options have been
 set). This default implementation assumes all instance processing occurs
 during inputFormat() and input().
