    override func viewDidLoad() {

        super.viewDidLoad()

        list = [ ghost(name:"alphabet".localized, id:"1"),
             ghost(name:"élephant".localized, id:"2"),
             ghost(name:"delegate".localized, id:"3")]
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return 1 
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if filtering() { 
            return filter.count 
        }
        return list.count 
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "library", for: indexPath)
        var data: ghost

        if filtering() { 
            data = filter[indexPath.row] 
        }
        else { 
            data = list[indexPath.row] 
        }

        cell.textLabel!.text = data.name
        return cell 
    }
