* 1. Locate the OnCreate method in MainActivity.cs.
* 2. Comment out the existing ListAdapter assignment.
* 3. Load the data using SongLoader.Load. This method uses the Task based Async pattern; you will need to await the call and decorate OnCreate with the async keyword.
* 4. Call ToList on the IEnumerable<Song> returned from SongLoader.Load - we'll use this in the next step. (This will require the System.Linq namespace.)
* 5. Create a new ListAdapter<Song> and assign the following properties:
* 6. Set the DataSource property to your new list.
* 7. Set the TextProc to a lambda that returns the song name: s => s.Name.
* 8. Set the DetailTextProc to a lambda that returns the artist and album: s => s.Artist + " - " + s.Album.
* 9. Assign the object to the ListAdapter property.
