+    # [scope]
+    #
+    #   A Proc or a Hash used to scope out grid data. The Proc will receive the current relation as a parameter and must
+    #   return the modified relation. For example:
+    #
+    #      class Books < Netzke::Grid::Base
+    #        def configure(c)
+    #          super

+    #          c.scope = lambda {|r| r.where(author_id: 1) }
+    #        end
+    #      end
+    #
+    #   Hash is being accepted for conivience, it will be directly passed to `where`. So the above can be rewritten as:
