[stringtemplate-interest] AttributeProvider interface

[Collin Fagan]

Yes as I said I've implemented model adapters to get results very much like
what I'm asking for.

But a model adapter only controls what happens 'after the dot'. I want to
provide the actual variables.

<beanFromSpring.dataIneed>

instead of

<context.beanFromSpring.dataIneed>
