/// Tasks in a project are organized as a rooted hierarchical tree structure, with a root task and subtrees of children tasks. 
/// <p>To build a tree of tasks one can use a specialized collection <see cref="Aspose::Tasks::TaskCollection"></see> by accessing <see cref="Project::RootTask"></see> property e.g.:</p>
/// <code>
/// Project project = new Project();
/// 
/// // add new tasks
/// Task task1 = project.RootTask.Children.Add(); // a parent task with empty name is added
/// Task childTask1 = task1.Children.Add("Child 1");
/// childTask1.Set(Tsk.Start, new DateTime(2020, 2, 12, 8, 0, 0))
/// childTask1.Set(Tsk.Duration, project.GetDuration(8, TimeUnitType.Hour));
/// childTask1.Set(Tsk.Finish, new DateTime(2020, 2, 12, 17, 0, 0));
