### addLateHeaderFooter

    public void addLateHeaderFooter(HeaderFooterRecord rec)

  HEADERFOOTER is new in 2007. Some apps seem to have scattered this record long after the `PageSettingsBlock` where it belongs.

  Parameters:
    `rec` - the HeaderFooterRecord to set

### addLateRecords

    public void addLateRecords(RecordStream rs)

  This method reads PageSettingsBlock records from the supplied RecordStream until the first non-PageSettingsBlock record is encountered. As each record is read, it is incorporated into this PageSettingsBlock.

  The latest Excel version seems to write the PageSettingsBlock uninterrupted. However there are several examples (that Excel reads OK) where these records are not written together:

  - HEADER_FOOTER(0x089C) after WINDOW2 - This record is new in 2007. Some apps seem to have scattered this record long after the PageSettingsBlock where it belongs test samples: SharedFormulaTest.xls, ex44921-21902.xls, ex42570-20305.xls
  - PLS, WSBOOL, PageSettingsBlock - WSBOOL is not a PSB record. This happens in the test sample file "NoGutsRecords.xls" and "WORKBOOK_in_capitals.xls"
  - Margins after DIMENSION - All of PSB should be before DIMENSION. (Bug-47199)
  These were probably written by other applications (or earlier versions of Excel). It was decided to not write specific code for detecting each of these cases. POI now tolerates PageSettingsBlock records scattered all over the sheet record stream, and in any order, but does not allow duplicates of any of those records.

  Note - when POI writes out this PageSettingsBlock, the records will always be written in one consolidated block (in the standard ordering) regardless of how scattered the records were when they were originally read.

  Parameters:
    `rs` - the RecordStream to read from
  Throws:
    `RecordFormatException` - if any PSB record encountered has the same type (sid) as a record that is already part of this PageSettingsBlock

### positionRecords

    public void positionRecords(java.util.List<RecordBase> sheetRecords)

  Some apps can define multiple HeaderFooterRecord records for a sheet. When saving such a file Excel 2007 re-positions them according to the following rules: - take a HeaderFooterRecord and read 16-byte GUID at offset 12. If it is zero, it means the current sheet and the given HeaderFooterRecord belongs to this PageSettingsBlock - If GUID is not zero then search in preceding CustomViewSettingsRecordAggregates. Compare first 16 bytes of UserSViewBegin with the HeaderFooterRecord's GUID. If match, then append the HeaderFooterRecord to this CustomViewSettingsRecordAggregates

  Parameters:
    `sheetRecords` - the list of sheet records read so far
