  // cases where Self is of type NodeRepresentable. 
  // This means we don't have to provide our own makeJSON() 
  // method if the extension satisfies our needs
  
  // ResponseRepresentable requires a single function
  // makeResponse() throws -> Response
  func makeResponse() throws -> Response {
