Question about

Hi the KNIME team,

here are a two question about SortedTable:

* SortedTable iterator returns a CloseableRowIterator but not a RowIterator . Looking at the source, I saw that this iterator is a CloseableRowIterator; Any reason for this ?

* SortedTable : after I used a SortedTable, should I release/dispose something ? In general, for any implementation of the DataTable in the KNIME API, is there something to do to release some temporary respources ( DataTable created but not returned by 'model.execute()'  )
