passing dictionaries through COM

Hi,

there is no such type as mapping in oleautomation. If you
want to have a mapping type you must pass an object which 
behaves like a dictionary. A sample COM server which acts
like a dictionary is in 

%PythonRoot%\win32com\servers\dictionary.py

How to wrap Python objects as return values in COM servers could 
be in the book of Mark and Andy.
