-/**

-* Class for writing Excel BIFF records.

-* 

-* From "MICROSOFT EXCEL BINARY FILE FORMAT" by Mark O'Brien (Microsoft Corporation):

-*

-* BIFF (BInary File Format) is the file format in which Excel documents are 

-* saved on disk.  A BIFF file is a complete description of an Excel document.

-* BIFF files consist of sequences of variable-length records. There are many 

-* different types of BIFF records.  For example, one record type describes a 

-* formula entered into a cell; one describes the size and location of a 

-* window into a document; another describes a picture format.
