class Blacklight::Solr::FacetPaginator

Pagination for facet values – works by setting the limit to max displayable. You have to ask Solr for limit+1, to get enough results to see if 'more' are available'. That is, the all_facet_values arg in constructor should be the result of asking solr for limit+1 values. This is a workaround for the fact that Solr itself can't compute the total values for a given facet field, so we cannot know how many “pages” there are.
