* Reading and Writing support for Excel '97(-2003) (BIFF8) file format.
* Low level structures for BIFF(Binary Interchange File Format).
* Low level structures for compound document file format (also known as "OLE2 storage file format" or "Microsoft Office compatible storage file format").

FastExcel is content-based,that means we just care about the content of excel. So FastExcel just read the cell string and other important information,Some Properities like color,font are not supported.Because we don't need to read,parse,store these additional information so FastExcel just need little memory.
