  36.  * - Src:/home/test/ ,Dst:/home/ ,Result:/home/**-> if source was direcotry copy its content to dest
  37.  * - Src:/home/test ,Dst:/home/test2 ,Result:/home/test2/** -> if source was directoy copy it and its content to dest with test2 as name

  40.  * - Should have rollback so it can undo the copy when it wasn't completely successful
  41.  * - It should be possible to turn off auto path creation feature f
  42.  * - Supporting callback function
