# = Introduction
# Blacklight::Solr::Document is the module with logic for a class representing
# an individual document returned from Solr results.  It can be added in to any
# local class you want, but in default Blacklight a SolrDocument class is
# provided for you which is pretty much a blank class "include"ing
# Blacklight::Solr::Document.
#
# Blacklight::Solr::Document provides some DefaultFinders.
#
# It also provides support for Document Extensions, which advertise supported
# transformation formats.
