/**
* 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>
