[antlr-interest] "Actions, however, can ask for the hidden channel tokens."

[Terence Parr]

the token stream has a buffer of all tokens on all channels.  if your  
token is t, then i=t.getTokenIndex() or whatever will give you an  
index. Then look at tokensStream.get(i-1) and -2 etc... to see if  
their t.getChannel() is hidden.
