//
 //  Function to create or update a cookie.
 //    name - String object object containing the cookie name.
 //    value - String object containing the cookie value.  May contain
 //      any valid string characters.
 //    [expires] - Date object containing the expiration data of the cookie.  If
 //      omitted or null, expires the cookie at the end of the current session.
 //    [path] - String object indicating the path for which the cookie is valid.
 //      If omitted or null, uses the path of the calling document.
 //    [domain] - String object indicating the domain for which the cookie is
 //      valid.  If omitted or null, uses the domain of the calling document.
 //    [secure] - Boolean (true/false) value indicating whether cookie transmission
 //      requires a secure channel (HTTPS).  
 //
 //  The first two parameters are required.  The others, if supplied, must
 //  be passed in the order listed above.  To omit an unused optional field,
 //  use null as a place holder.  For example, to call SetCookie using name,
 //  value and path, you would code:
 //
 //      SetCookie ("myCookieName", "myCookieValue", null, "/");
 //
 //  Note that trailing omitted parameters do not require a placeholder.
 //
 //  To set a secure cookie for path "/myPath", that expires after the
 //  current session, you might code:
 //
 //      SetCookie (myCookieVar, cookieValueVar, null, "/myPath", null, true);
