  1. start task,
      parameters:
      - scenario for extension: 1
      - task name in gryzzly adams: medusae
      - monster count: 500
      - monster name to track: medusa
      - optional, monster name 2: 
  2. check status, 
      to be used on refill to decide whether to go back or spawn or go give task back
      parameters:
      - scenario for extension: 2
      - label if task in progress: skipTask
      - label if task done: taskDone  
  3. report task,
      parameters:
      - scenario for extension: 3
  
  Strong suggestion, almost mandatory - USE POS CHECK to verify position! this module will only check if there is ANY npc in range!

  when begin remove all the text and leave just a single string of parameters
  some examples:

  2, skipReport, goReport
  3
  1, drakens, 500, draken warmaster, draken spellweaver
  1, medusae, 500, medusa]],
