** HListItems is uses an array-packed list of hash objects as its value.
** Each item in the array should have a 'label' and a 'value' key.
** The 'label' key of each item is used as the label for the HRadiobutton in the list.
** The 'value' key of each item is the value used for the output.
** The parent object of a HListItem needs to be a compatible hash, like HRadiobuttonList.
