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. 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.
 - 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.

because CSS/JS/images are all too complicated for us.
