[stringtemplate-interest] Renderer "modes"

[Jeremy Gray]

Hmm. I hadn't realized that subclassing ST was an option, and admittedly
didn't gather that impression from your papers. Still, I am not having
an easy time imagining how auto-wrapping all dates would allow for the
conditional behaviour I was describing where a date might be formatted
one way once in a template and another way elsewhere. Perhaps something
just hasn't clicked in my mind yet. I'll have to think about it for a
bit.

Just wrap the dates in an object that delegates.  getMedium() would  
call the formatted on the wrapped object. :)

No need for a renderer really...just wrap automatically by  
subclassing StringTemplate and having it auto-wrap all Dates. :)   
Works great.
