set it as drawable top
I want to set drawable top/right/left/bottom.
I tried something like this

```
textView_main_updated.setCompoundDrawables(new IconicsDrawable(context, FontAwesome.Icon.faw_android).color(Color.GREEN),null,null, null);
new Iconics.IconicsBuilder().ctx(context).on(textView_main_updated).build();
```

but it doesn't work. am I doing something wrong ?
