How to bind actions and classes

How can I bind `actions` and `classes`?

I expected something like:
```
<pell-editor [actions]="['bold', 'underline']" [classes]="{actionbar: 'pell-actionbar'}"></pell-editor>
```

But it seems like the component has no `@Input()`: https://github.com/sabakugaara/angular-pell/blob/master/src/app/modules/pell/pell.component.ts
