Pure Ruby message threading based on the algorithm described by
JWZ in <https://www.jwz.org/doc/threading.html> and used in
countless mail and news readers; but with some features removed
and improved flexibility:

* Message format-agnostic, not limited to email or NNTP;
  but even appropriate for forums, blog comments, IM, etc.
  For mail and NNTP messages, that means you must extract
  the Message-ID and parse the References and In-Reply-To
  headers into an array yourself.

* No recursion; all algorithms are non-recursive to avoid
  SystemStackError exceptions in deep message threads.
  Memory usage is bound by the number of lightweight containers
  needed to represent a thread.

* No pruning of non-leaf ghosts.  Readers are not shielded
  from deleted or lost messages.  Equivalent to setting
  "hide_missing" to "no" in mutt.

* No grouping by subject[1].  This makes things ideal for short
  messages such as chat and status updates.  For email, this
  encourages the use of proper client which set In-Reply-To
  or References headers.  Equivalent to setting "strict_threads"
  to "yes" in mutt.

  [1] - Instead, messages with the same Subject can be grouped
        by a search engine.  For email, this would be done using
        a mail search engine like notmuch or mairix.
