| /** |
| * Title: Recalc Id Record<P> |
| * Description: This record contains an ID that marks when a worksheet was last |
| * recalculated. It's an optimization Excel uses to determine if it |
| * needs to recalculate the spreadsheet when it's opened. So far, only |
| * the two values <code>0xC1 0x01 0x00 0x00 0x80 0x38 0x01 0x00</code> |
| * (do not recalculate) and <code>0xC1 0x01 0x00 0x00 0x60 0x69 0x01 |
| * 0x00</code> have been seen. If the field <code>isNeeded</code> is |
| * set to false (default), then this record is swallowed during the |
| * serialization process<P> |
| * REFERENCE: http://chicago.sourceforge.net/devel/docs/excel/biff8.html<P> |
