   * Step 1 : createTask()
   *          - will create a gelato task
   *          - will store the taskId
   *
   * Step 2 : checkerstartParty() Function.
   *          - Check If the task can be executed , in rhis case if we don't headache
   *          - returns the execPayload of startParty()
   *
   * Step 3 : Executable Function: startParty()
   *          - will Start the party setting lastPartyStrt to block.timestamo
   *          - will cause a headache
