/**
 * This is basically a kludge to deal with the now obsolete Label records.  If
 * you have to read in a sheet that contains Label records, be aware that the rest
 * of the API doesn't deal with them, the low level structure only provides read-only
 * semi-immutable structures (the sets are there for interface conformance with NO
 * Implementation).  In short, you need to call this function passing it a reference
 * to the Workbook object.  All labels will be converted to LabelSST records and their
 * contained strings will be written to the Shared String table (SSTRecord) within
 * the Workbook.
 *
 * @param records a collection of sheet's records.
 * @param offset the offset to search at
 * @see org.apache.poi.hssf.record.LabelRecord
 * @see org.apache.poi.hssf.record.LabelSSTRecord
 * @see org.apache.poi.hssf.record.SSTRecord
