// document, with a specified name and optional attributes.
// Arguments:
//   document: The Document object that the cookie is stored for. Required.
//   name:     A string that specifies a name for the cookie. Required.
//   hours:    An optional number that specifies the number of hours from now
//             that the cookie should expire.
//   path:     An optional string that specifies the cookie path attribute.
//   domain:   An optional string that specifies the cookie domain attribute.
//   secure:   An optional Boolean value that, if true, requests a secure cookie.
//
