  This partial renders a div with two spans that are suitable for use as
  previous and next buttons when properly styled.
  - You probably need a class in order to render this properly.
  - :klass          - pass in this local to specify a class for the containing div.
  - :label_previous - the label for the Previous button. Default is "Previous".
  - :label_next     - the label for the Next button. Default is "Next".
