[antlr-interest] Default error handler, generated _token_set_n

[Ingo Maier]

Hi,

the default parser error handler seems to catch RecognitionExceptions
and then calls consumeUntil() with an auto generated BitSet as argument
(_token_set_n). I guess these BitSets contain some hint to synchronizing
tokens?  But how exactly? I couldn't fiddle out by myself nor found it
in the docs.

Thanks,
Ingo
