Is there a way to include "show_mode" in the SwipeLayout definition in the xml file?

This is one of the best solutions I have found for swipe-action implementation in Android. :+1: for a great job!

My comment was about this line:

```
swipeLayout.setShowMode(SwipeLayout.ShowMode.LayDown);
```

If there was a way to specify the show mode in the XML file itself instead of in code, that would be great. Like so:

```

. . .
