  24 this class is here to import tasks from a planner project file to ktimetracker.
  25 the import shall not be limited to ktimetracker (kPlaTo sends greetings)
  26 it imports planner's top-level-tasks on the same level-depth as currentItem.
  27 if there is no currentItem, planner's top-level-tasks will become top-level-tasks in ktimetracker.
  28 it imports as well the level-depth of each task, as its name, as its percent-complete.
  29 test cases:
  30  - deleting all tasks away, then import!
  31  - having started with an empty ics, import!
  32  - with currentItem being a top-level-task, import!
  33  - with currentItem being a subtask, import!
