  //       Currently in checklist all are set as uncompleted/not checked,
  //       IFTTT Rule does not move card to other list.
  //       If following line is negated/changed to:
  //         if(!checkList.isFinished()){
  //       then unchecking of any checkbox will move card to other list,
  //       even when all checkboxes are not yet unchecked.
  //       What is correct code for only moving when all in list is unchecked?
  // TIPS: Finding  files, ignoring some directories with grep -v:
  //         cd wekan
  //         find . | xargs grep 'count' -sl | grep -v .meteor | grep -v node_modules | grep -v .build
  //       Maybe something related here?
