   [getCookieValue ck] returns SOME(v) where v is the value associated
   with the cookie ck, if any; otherwise returns NONE.

   [getCookie ck] returns SOME(nv) where nv is the ck=value string
   for the cookie ck, if any; otherwise returns NONE.

   [allCookies] is a list [nv1, nv2, ..., nvm] of all the ck=value
   pairs of defined cookies.

   [setCookie { name, value, expiry, domain, path, secure }] returns a
   string which (when transmitted to a browser as part of the HTTP
   response header) sets a cookie with the given name, value, expiry
   date, domain, path, and security.

   [setCookies ckds] returns a string which (when transmitted to a
   browser as part of the HTTP response header) sets the specified cookies.

   [deleteCookie { name, path }] returns a string which (when
   transmitted to a browser as part of the HTTP response header)
   deletes the specified cookie by setting its expiry to some time in
   the past.
