[stringtemplate-interest] Set up template attributes with external method call

[Collin Fagan]

Hi Ben,

You might want to look at writing model adapters to "add" the properties you
want to the object hierarchy you are stuck with.

I have some examples on the strum page.

http://sourceforge.net/apps/mediawiki/project-strum/index.php?title=Main_Page

The basic idea is "hey ST when you see this attribute on this class do *
this".
*
I hope this helps,

Collin
