    Edson's new parser is almost finished. We just found we had hit a
    brick will with pure ANTLR, it was defying us at every turn. Which
    caused our language innovation to crawl to a halt. It's been very
    painful, but once it's done, we'll be back on the language
    innovation train again :)<br>

                                        <br>
                                        I'm adding support for
                                        "otherwise" to (for the time
                                        being) the guided decision table
                                        in Guvnor.<br>
                                        <br>
                                        The idea being if you set a cell
                                        to represent "otherwise" the
                                        generated rule is the opposite
                                        of the accumulation of the other
                                        cells; perhaps best explained
                                        with an example:-<br>

                                        </div>
