  This generator makes the following changes to your app:
   1. Creates a new SearchBuilder class that inherits from Hyrax::CatalogSearchBuilder
   2. Adjusts config.search_builder_class settings in CatalogController
   3. Adds configuration to config.advanced_search settings in CatalogController
   4. Adds an initializer to patch some BlacklightAdvancedSearch classes to allow for date range searches
