/**
 * Set a cookie, or unset it by passing -1 as the expires param
 *
 * It is very important to pass *exactly* what was used to set the cookie in
 * the first place - this means same name, path, domain and secure. If the
 * cookie is host-only (had no domain passed in when set) then pass null as
 * the domain parameter, however if a domain was used when the cookie was
 * set then it will need a peiod prefix (.www.whatever.com) as the domain
 *
 * @param String name    The cookie name
 * @param String value   What to set to, use '' to unset
 * @param Int    expires Expiry in seconds, -1 to unset
 * @param String path    The path, when unsetting must be exactly as when set
 * @param String domain  The domain, when unsetting must be exactly as when set
 * @param Bool   secure  Secure or not, when unsetting must be exactly as when set
 *
 * @return void
