	      is_auto_increment => 1,
	   },
	   kitten => {

DESCRIPTION
       This component automatically removes "heavy-weight" columns.  To be specific, columns of type "text", "ntext", "blob", "clob", or "bytea".
       You may use the "remove_column" key in the column info to specify directly whether or not to remove the column automatically. See "NOTE" in
       DBIx::Class::Helper::ResultSet for a nice way to apply it to your entire schema.

METHODS
   _should_column_fetch
	$self->_should_column_fetch('kitten')

       returns true if a column should be fetched or not.  This fetches a column if it is not of type "text", "ntext", "blob", "clob", or "bytea"
       or the "remove_column" is set to true.  If you only wanted to explicitly state which columns to remove you might override this method like
       this:

	sub _should_column_fetch {
	   my ( $self, $column ) = @_;

	   my $info = $self->column_info($column);

	   return !defined $info->{remove_column} || $info->{remove_column};
	}

   fetchable_columns
       simply returns a list of columns that are fetchable.
