Major, major re-organisation of OLE code with a view towards getting it into 

a library. Very little real code change there, mostly shuffling.
Similar cosmetic cleanups to ms-excel.c, and a few little features fixed.

View file @ a9475d31
1998-11-12 Michael Meeks <michael@imaginator.com>
* plugins/excel/ms-ole.c, plugins/excel/ms-ole.h: Massive changes
renamed many functions to conform to a sensible naming convention.
Cleaned the interface, and structure names.
* plugins/excel/ms-excel-biff.h: Split from ms-biff.h removing all
the excel specifics so that the biff & ole stuff can be turned into
a library sometime.
* src/workbook.c(workbook_read): Updated to new structure names.
* plugins/excel/ms-excel.c: Added list of array formulae, as yet
unused, possibly unneccesary.
* plugins/excel/ms-formula.c: Added support for slightly different
array formula BIFF layout.
1998-11-11 Miguel de Icaza <miguel@nuclecu.unam.mx>
* src/gnumeric-util.c (font_get_italic_name): Missing function.
