/*

The HANSARDLIST class and its children, DEBATELIST and WRANSLIST, display data about
Hansard objects. You call display things by doing something like:

        $LIST = new DEBATELIST;
        $LIST->display('gid', array('gid'=>'2003-10-30.422.4') );

    The second line could be replaced with something like one of these:

        $LIST->display('date', array('date'=>'2003-12-31') );
        $LIST->display('recent');
        $LIST->display('member', array('id'=>37) );


Basic structure...

    The display() function calls a get function which returns all the data that
    is to be displayed. The function name depends on the $view (ie, 'gid', 'recent',
    etc).
    Once we have an array of data, the render() function is called, which includes
    a template. This cycles through the data array and outputs HTML.

    Most of the data is fetched from the database by the _get_hansard_data() function.

    The COMMENTSLIST class is simpler and works in a similar fashion - that might help
    you get your head round how this all works...

Future stuff...

    You could have multiple templates for different formats. Eg, to output stuff in
    XML, duplicate the HTML template and change what you need to create XML instead.
    Then call the display() function something like this:
        $LIST->display('gid', array('gid'=>'2003-10-30.422.4'), 'xml' );
    (You'll need to allow the 'xml' format in render() too).

    No support for pages of results yet. This would be passed in in the $args array
    and used in the LIMIT of the _get_hansard_data() function.
    The template could then display links to next/prev pages in the sequence.
