[antlr-interest] Token Attributes in Arraylist

[Alexander Gängel]

Thank you this work very well,

I was just wondering if there is some way in Antlr already cause this 
way I don't use the id+= operator and Coding in Antlrworks is with out 
knowing all methods the CommenTree in the ArrayList from id+= is a bit 
difficult so I would think it would be handy to use the attributes Antlr 
gives on the Tokens also on the ArrayList.
