%    The proof environment is never numbered, and has a \cn{qed} at
%    the end, which makes it inconvenient to use \cn{newtheorem} for
%    defining it. Also authors frequently need to substitute an
%    alternative heading text (e.g. `Proof of Lemma 4.3')
%    instead of the default `Proof'. For all these reasons we define
%    the proof environment here instead of leaving it for authors to
%    define.
