fdo77985 Calc function NETWORKDAYS

[Winfried Donkers]

Hi Eike,

>Rather implement an ODFF compliant NETWORKDAYS function at the interpreter that shares implementation with ScNetWorkdays_MS() (syntax and semantics are equal, aren't they? I didn't look up now) and rename the Add-In one to NETWORKDAYS_ADD, note that this will also need adapting the entry in sc/source/core/tool/odffmap.cxx and the entries in the mappings of sc/source/filter/excel/xlformula.cxx and sc/source/filter/oox/formulabase.cxx, the latter may probably write NETWORKDAYS.INTL for the ODFF NETWORKDAYS. I'll help you to figure out details.

It seems that function NOMINAL is both an Add-in and a regular calc function. 
I will see if I can copy that principle for NETWORKDAYS.
