Description:
------------
Now when extending Spreadsheet_Excel_Writer_Workbook class there is no way to return extended classes for *_Worksheet, *_Format, etc. from ->addWorksheet(), ->addFormat(), etc...

I sudgest to add additional parameter for those methods - $className:

< function &addWorksheet($name = '')
> function &addWorksheet($name = '', $className = '')

< function &addFormat($properties = array())
> function &addFormat($properties = array(), $className = '')

...

And then reimplement thouse methods to support different classes:

< $worksheet = new Spreadsheet_Excel_Writer_Worksheet(...

> if (! class_exists($className)) {
> $className = 'Spreadsheet_Excel_Writer_Worksheet';
> }
> $worksheet = new $className(...
> if (! is_a($worksheet, 'Spreadsheet_Excel_Writer_Worksheet')) {
> $this->raiseError('Custom class do not extends Spreadsheet_Excel_Writer_Worksheet', 0, PEAR_ERROR_DIE);
> }

...and the same for all other classes.
