[antlr-interest] Generating initializers and headers

[Nikolas Everett]

So far I think I have two options:

1.  Create a custom StringTemplateGroup which provides string templates that
proxy calls to all the StringTemplates that I'm going to need.  I could pull
out all the stringtemplates that I need and build the files with them.
That'd be simple enough.
2.  Create seperate template grammars that build everything I need.

I'll poke around with these two options and let the group know what I did.

Thanks for the help.
