Strange exports of module in node

After install with NPM `npm install guesslanguage`
I have strange behaviour when importing.
Seems like the module exports a JS object  so i have to duplicate and write  `guessLanguage.guessLanguage.detect`

here an example in coffeescript

``` javascript
guessLanguage = require 'guesslanguage'
guessLanguage.guessLanguage.detect text, (language) ->
        console.log "language is : "+language
```
