positive.code: <%# like Blacklight _facet_limit.html.erb , displays an individual
      sidebar facet list. 
  
      locals required:
        * solr_field: name of facet field configured in BL configuration (passed in by standard BL)
        * One of EITHER:
          * display_facet: (passed in by standard BL)
          * paginator: Blacklight::FacetPaginator, passed in by our BlacklightFacetBrowse
            action, when retrieving AJAX results for sidebar. 
  
      But we add a search
      box, with ajax instant search -- we're actually
      going to call out to the existing facet_limit, woot! 
  
      If you want searchable box in sidebar facet, you configure
      use of this partial in your facet configuration (such as in catalogcontroller),
      eg
  
          config.add_facet_field  "subject_topic_facet", :label => "Topic", 
            :limit => true, :browse_field => "subject_topic_browse_facet",
            :partial => "browsable_facet_limit"
  
  
negative.code: 
  <%-
  unless local_assigns[:paginator]
    paginator =
      Blacklight::Solr::FacetPaginator.new(display_facet.items,
        :limit => facet_limit_for(solr_field))
  end
  -%>
