// Get and set cookies

// The browser thinks cookies are strings.  So we've wrapped them in JSON
// serialize and de-serialize so we can pretend they are *actually* JS
// objects.

// Cookie management code via blazonry.com/javascript/cookies.php with flavor
// Expires behaves badly if your browser is set to flush all cookies at the
// end of the session It never records the expire date at all, just sets
// everything to "end of session" (AFAICT) Must wonder what this does to
// cookies that are set for, say, 3 seconds in the future?

// All date code in here now.  I don't want to think about the details.
// Everytime we write a cookie it will get a new expiredate
