        Created to solve the key deficiently with MultiRegex - there is no way to
        test for multiple matches at a single location.  Why would we need to do
        that?  In the future a more dynamic engine will allow certain matches to be
        ignored.  An example: if we matched say the 3rd regex in a large group but
        decided to ignore it - we'd need to started testing again at the 4th
        regex... but MultiRegex itself gives us no real way to do that.

        So what this class creates MultiRegexs on the fly for whatever search
        position they are needed.

        NOTE: These additional MultiRegex objects are created dynamically.  For most
        grammars most of the time we will never actually need anything more than the
        first MultiRegex - so this shouldn't have too much overhead.

        Say this is our search group, and we match regex3, but wish to ignore it.

          regex1 | regex2 | regex3 | regex4 | regex5    ' ie, startAt = 0

        What we need is a new MultiRegex that only includes the remaining
        possibilities:

          regex4 | regex5                               ' ie, startAt = 3

        This class wraps all that complexity up in a simple API... `startAt` decides
        where in the array of expressions to start doing the matching. It
        auto-increments, so if a match is found at position 2, then startAt will be
        set to 3.  If the end is reached startAt will return to 0.

        MOST of the time the parser will be setting startAt manually to 0.
