//<!--WPF: this nested ItemsControl allows for placement of items on a screen based on bound properties-->
//<!--A key factor to make this work is the Content="{Binding}" statement on line 33, as this links the items to the ItemControl's datacontext-->
//<!--Collections must be of type ObservableCollection<T> for XAML to register updates to the collection-->
