// Example of TTasks.
// Create a hierarchy of objects derived from TTask in library Mytasks
// Show the tasks in a browser.
// To execute a Task, use the context context menu and select
// the item "ExecuteTask"
// see also other functions in the TTask context menu, such as
//   -setting a breakpoint in one or more tasks
//   -enabling/disabling one task, etc
