[antlr-interest] Binary support

[Sam Barnett-Cormack]

I did some work with ASN.1 a while back. If it weren't for some ethical 
issues, I'd go back to doing it on my own time, to try and make a 
java-based tool to handle ASN.1 stuff. The problem with ASN.1 is - what 
bit of it are you talking about? Which encoding? How feature-complete? 
Which version? It's all a bit foggy. It would also only be helpful for 
any binary format which could be described using ASN.1, which isn't 
quite all of them.
