[Zope] return structured result from Python scripts for page templates

[Chris McDonough]

Use an external method, and return instances of "security-aware" 
classes.  See the section entitled "Class Security Assertions In 
Non-Product Code (External Methods/Python Scripts)" in the Zope 
Developer's Guide Security chapter 
(http://www.zope.org/Documentation/ZDG/Security.stx).

I usually just return a dictionary for this purpose, though.  That's 
really all an instance is anyway if you don't have any methods. ;-)
