* Low level model implementation of a Sheet (one workbook contains many sheets)
* This file contains the low level binary records starting at the sheets BOF and
* ending with the sheets EOF. Use HSSFSheet for a high level representation.
*
* The structures of the highlevel API use references to this to perform most of their
* operations. Its probably unwise to use these low level structures directly unless you
* really know what you're doing. I recommend you read the Microsoft Excel 97 Developer's
* Kit (Microsoft Press) and the documentation at http://sc.openoffice.org/excelfileformat.pdf
* before even attempting to use this.
