0.2.2 (2003-10-08):
- Cleaned up class.writeexcel_biffwriter.inc.php
- Cleaned up _append() and _prepend() in class.writeexcel_biffwriter.inc.php
  and class.writeexcel_worksheet.inc.php to no longer use func_get_args()
  but require exactly one argument instead (internal api change)
- Changed class to support tmpfile. Because of this it is possible now to
  create an excel sheet on the fly that can be send by web server and is
  afterwards deleted. To provoke this behaviour you just pass an empty file
  name and later on use the writexcel_workbook->send(filename) function.
  (contributed by Andreas Brodowski)

  formulas in worksheets (contributed by Andreas Brodowski)
