/**
|
|
* Title: Recalc Id Record (0x01C1)<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/>
