**BREAKING CHANGES**

* functions are now directly exposed on the module object:
```js
require('isbn2').ISBN.parse('1933988037').codes.isbn13h // => '978-1-933988-03-0'
// becomes
require('isbn3').parse('1933988037').isbn13h // => '978-1-933988-03-0'
```

* added a [command-line interface](https://github.com/inventaire/isbn3#CLI)
* [expose groups data on the module object](https://github.com/inventaire/isbn3#groups)
* recover common hyphenization mistake `979-1091146135`
