 ## search_dimensions integration
 
 The file `lib/ntee/search_dimension.rb` defines a few classes you can use in conjunction with Gively's `search_dimensions` gem to deal with NTEE categories stored in a Solr search index.  `NTEE::HierarchicalDimension` lets you treat the categories as a hierarchical tree, and `NTEE::FlatDimension` lets you treat them as a plain string field.
