test/check_cnp: working algorithm

I now have a working algorithm in test/check_cnp.  It can correctly
parse the grammar for an esoteric language called "Brainfuck".  This
language does not matter.  What matters is that it contains
parentheses.  So this shows that at least for grammars as complex as
parentheses, this parser works well.  Haha.
