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.

all_facet_values is a list of facet value objects returned by solr, asking solr for n+1 facet values. options: :limit => number to display per page, or (default) nil. Nil means
display all with no previous or next.
:offset => current item offset, default 0 :sort => ‘count’ or ‘index’, solr tokens for facet value sorting, default ‘count’.
