      public class AddScreenTask
      extends ComponentTask

  Adds a new screen instance to a Layout, as a new Tab in a TabSet or as a new Section in a SectionStack. When the target is a TabSet or SectionStack, a static `title` or dynamic `titleFormula` can be assigned for the new Tab or Section.

  The new screen's `dataContext` can be configured with `dataContextBinding` evaluated in the scope of this task.
