formatter is a library for formatting text.

The `Formatter` wraps an `io.Writer` and formats text written to it. It enables text indenting

and line width wrapping.

#### Examples

```golang

// Create a new formatter.

f := Formatter{

    // For formatter wraps a writer. The writer is where the output will be written to.

    Writer: os.Stdout,

    // Define text indentation. This could be spaces, tabs or any other character set. It will

    // be inserted in the beginning of the text and after every new line. Leave it nil for not

    // indenting the text.

    Indent: []byte(">  "),

    // Width defines line width for applying line wrap. Any non-positive number will be ignored.

    Width: 80,

}

// Writing into the formatter will result in the formatted text being written into the defined

// `Formatter.Writer`.

_, err := f.Write([]byte(loremIpsum))

if err != nil {

    // Handle error :-)

    panic("failed writing Lorem Ipsum")

}

```

 Output:

```

>  Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod

>  tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,

>  quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo

>  consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse

>  cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
