When testing the class, I had two php notices ("Notice: Use of undefined constant safe - assumed 'safe' in").

After investigation, you must replace (2 times) :

```
if(is_callable(array(safe, 'filter_'.$filter)))
```

by :

```
if(is_callable(array(__CLASS__, 'filter_'.$filter)))
```

Very nice project !
