Hash hacks so that CouchRest::Document plays nice with Rails routes

ugly couchrest hacks.rb

# Hacks so that CouchRest::Document, which descends from Hash,
# doesn't appear to Rails routing as a Hash of options

      return false if o == Hash
      super
    end
    alias_method :kind_of?, :is_a?
  end
end

class Model < CouchRest::Document; end
