/*
    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.

      // all prior rules are also skipped which can result in matching the wrong
      // thing. Example of matching "booger":

// our matcher is [string, "booger", number]
      //
      // ....booger....

// if "booger" is ignored then we'd really need a regex to scan from the
      // SAME position for only: [string, number] but ignoring "booger" (if it
      // was the first match), a simple resume would scan ahead who knows how
      // far looking only for "number", ignoring potential string matches (or
      // future "booger" matches that might be valid.)

// So what we do: We execute two matchers, one resuming at the same
      // position, but the second full matcher starting at the position after:

//     /--- resume first regex match here (for [number])
      //     |/---- full match here for [string, "booger", number]
      //     vv
      // ....booger....

// Which ever results in a match first is then used. So this 3-4 step
      // process essentially allows us to say "match at this position, excluding
      // a prior rule that was ignored".
      //
      // 1. Match "booger" first, ignore. Also proves that [string] does non match.
      // 2. Resume matching for [number]

   *             - 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

   *
   *             - 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.
