* Last modified : 17 May 2001
* Desciption : This class is used to generate very simple
* MS Excel file (xls) via PHP.
* The generated xls file can be obtained by web as a stream
* file or can be written under $default_dir path. This package
* is also included mysql, pgsql, oci8 database interaction to
* generate xls files.
* Limitations:
* - Max character size of a text(label) cell is 255
* ( due to MS Excel 5.0 Binary File Format definition )
*
* Credits : This class is based on Christian Novak's small
* Excel library functions.
