      Usage::
  
          {% show_more %}
  
      Alternatively you can override the label passed to the default template::
  
          {% show_more "even more" %}
  
      You can override the loading text too::
  
          {% show_more "even more" "working" %}
  
      Must be called after ``{% paginate objects %}``.
