    If the "refChild" is null then the

    node "newChild" at the end of the list of children.

    Retrieve the second employee and invoke the
    "insertBefore(newChild,refChild)" method with
    refChild=null.   Since "refChild" is null the "newChild"
    should be added to the end of the list.   The last item
    in the list is checked after insertion.   The last Element
    node of the list should be "newChild".
