[stringtemplate-interest] updated codegen blog again

[Terence Parr]

Howdy,

More experience with the template refactoring in the v3 code  
generator...some interesting thoughts:

http://www.antlr.org/blog/antlr3/codegen.tml

The conclusion is that I may define "regions" within a template so  
you can override chunks of a template in a subgroup rather having to  
redefine the whole template. :)
