SugarRecord（Swift 1.2）を使ってCoreDataの操作を楽にしてみる ref: http://qiita.com/matsuhisa@github/items/499284a38733799117fa

        let stack: DefaultCDStack = DefaultCDStack(databaseName: "TestAppCocoaPods01.sqlite", automigrating: true)
        SugarRecord.addStack(stack)

        //ログレベルを設定(任意らしい)
        SugarRecordLogger.currentLevel = .logLevelError

        return true

    func name_plus() -> NSString{
        var neme_plus = self.name + "だよ"
        return neme_plus
