Writing a run-mode method: start()

Now, write a method for each mode in run_modes().

Start with the default run-mode, 'start':


    sub start {
        my $webapp = shift;
        my $query = $webapp->query;
        my $output;

        $output .= $query->start_html(-title =>
                                     "Welcome to St. Pat's Drink-o-Mat!");

        $output .= $webapp->drink_type_form;  # a method we'll add below...

        $output .= $query->end_html;

        return $output;
    }

The first argument passed into the method is the CGI::Application object itself
The return value gets sent to the browser.

(Should be a string containing a valid HTML page.)
