      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.

     *           but all content is held and added to the parent buffer rather than being
     *           output when the mode ends.  Mostly used with `sublanguage` to build up
     *           a single large buffer than can be parsed by sublanguage.
     *
     *             - The mode begin ands ends normally.
     *             - Content matched is added to the parent mode buffer.
     *             - The parser cursor is moved forward normally.
     *
     * @abort  - A hack placeholder until we have ignore.  Aborts the mode (as if it
     *           never matched) but DOES NOT continue to match subsequent `contains`
     *           modes.  Abort is bad/suboptimal because it can result in modes
     *           farther down not getting applied because an earlier rule eats the
     *           content but then aborts.
     *
     *             - The mode does not begin.
     *             - Content matched by `begin` is added to the mode buffer.
     *             - The parser cursor is moved forward accordingly.
     *
     * @ignore - Ignores the mode (as if it never matched) and continues to match any
     *           subsequent `contains` modes.  Ignore isn't technically possible with
     *           the current parser implementation.
     *
     *             - The mode does not begin.
     *             - Content matched by `begin` is ignored.
     *             - The parser cursor is not moved forward.
