[antlr-interest] Honey badger update: add auto generated visitors

[Terence Parr]

Hi..automatically generated visitors working. You can take a look at what they do at the bottom of this page:

http://www.antlr.org/wiki/display/ANTLR4/Examples

Very similar to listeners but useful in some cases. you can either, or, or both using commandline options.

you can grab the latest source tree:

https://github.com/antlr/antlr4

and run ant from the root.
