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