//  Function to create or update a cookie.

//    name - String 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.
