+* SOLR-3439: Make SolrCell easier to use out of the box. Also improves "/browse" to display
+  rich-text documents correctly, along with facets for author and content_type.  
+  With the new "content" field, highlighting of body is supported. See also SOLR-3672 for
+  easier posting of a whole directory structure. (Jack Krupansky, janhoy)
