Adding scroll control to the CarouselView

Add a new file into the Controls folder called CarouselScroll.cs and implement the first part as follows:

public class CarouselScroll : ScrollView 
  { 
    #region Private Properties
      private CarouselLayout _carouselLayout;
    #endregion
    public DataTemplate ItemTemplate
    {
      set
      {
        _carouselLayout.ItemTemplate = value;
      }
    }
    public CarouselScroll()
    {
      Orientation = ScrollOrientation.Horizontal;
      _carouselLayout = new CarouselLayout();
      Content = _carouselLayout;
     }
   }

The CarouselScroll will inherit the ScrollView object as this will be the bounding view for the CarouselLayout. We are also going to create a DataTemplate variable for setting the DataTemplate object inside the CarouselLayout. Then, in the constructor, we instantiate a new CarouselLayout object as the Content of the ScrollView.

Now let's add a custom binding object for the ItemsSource. Like a ListView, we will bind...
