```
public abstract class ViewGroupMixIn
extends Object
```
Implements ViewGroup to be used as a "mix-in". Not meant for a consumption from outside ViewGroups.
How to use this class
1. Create three data fields in your class:
```
 private String primaryView;
 private CopyOnWriteArrayList<View> views;
 private ViewsTabBar viewsTabBar;
 
```
2. Define a transient field and store ViewGroupMixIn subtype, then wire up getters and setters:
```
 private transient ViewGroupMixIn = new ViewGroupMixIn() {
     List<View> views() { return views; }
     ...
 }
 
```
