+=head2 Setting default values
+
+It's as simple as overriding the C<new> method. Note the use of C<next::method>.
+
+    sub new {
+        my( $class, $attrs ) = @_; 
+        
+        $attrs->{ foo } = 'bar' unless defined $attrs->{ foo };

+    }

+=head2 Stringification
+
+Deploy the standard stringification technique by using the C<overload> module. Replace
+C<foo> with the column/method of your choice.
