[antlr-interest] Comments get removed after instrumenting source

[Andreas Meyer]

If you just skip the comment token, it will be discarded. If you want to 
retain it, you have to use the "setHiddenAfter" / "setHiddenBefore" 
methods mentioned in the antlr wiki. Once the comments are stored there, 
you have to take care that you print them while traversing the tree for 
output.
