A rotating file Writer

```go

func ExampleWriter() {

	dir, err := ioutil.TempDir("", "rotate-test")

	if err != nil {

		panic(err)

	}

	defer os.RemoveAll(dir)

	const bytes3 int64 = 3

	w, err := rotate.NewWriter(dir, "test.log", rotate.WithSizeBasedPolicy(bytes3))

	if err != nil {

		panic(err)

	}

	defer w.Close()

	fmt.Fprint(w, "1")

	fmt.Fprint(w, "2")

	fmt.Fprint(w, "3")

	time.Sleep(time.Second) // wait for rotate

	fmt.Fprint(w, "4")

	b0, _ := ioutil.ReadFile(filepath.Join(dir, "test.log"))

	b1, _ := ioutil.ReadFile(filepath.Join(dir, "test.log.1"))

	fmt.Printf("%s/%s", b0, b1)

	// Output: 4/123

}
