[antlr-interest] StringTemplate does not work as expected using a simple string template group

[Kim Slattery]

To follow up, it had to do with the way I was outputting. I read something
in, I believe, the Language Implementation Patterns book and interpreted it
as, when printing the output, you need to call output.getTemplate().
However, that's definitely wrong. Most places, it says to call
output.toString(). My mistake.
