Fix atomic updates so they work (solr 4.6+), index all the sidecar objects for a doc, and install correctly into the SolrDocument
sidecar data should be indexed as *_tesim
add a sanity check to ensure we don't wipe out a solr document with an atomic update if there's no data
Facet fields should use :show configuration to toggle display, in case the facet fields also show up as constraints
Inject exhibit tags into the blacklight configuration
when creating the hash of tags to update, add an entry for all exhibits to ensure if the last tag for an exhibit is removed, we also remove the data from solr
link tags to a faceted search for that tag
