1. Contribute a view using the extension point views.
2. Implement and register a tree data provider to this contributed view using the API. API should be self explanatory.

What to Test ?

2. Make sure the extension is activated only when you expanded the view.
3. Make sure the command provided for tree item is called when the tree item is selected.
4. Make sure actions on title bar and on item are shown and called.
5. Make sure the view collapsible state and size is restored on refresh.

Play around and please provide feedback on the api and issues all through this repository.
