%% @doc Simple functions for generating HTML.  This first appeared
%%      in webmachine's wmtrace utility.  I'm extracting it to its
%%      own module for easy reuse.
%%      Example:
%%        html([],
%%             [body([],
%%                   [h1([], ["Hello, World!"]),
%%                    p([{"style", "font-type:italic"}],
%%                      "That's easy")
%%                   ])
%%             ])
%%      Should produce:
%%        <html><body>
%%        <h1>Hello, World!</h1>
%%        <p style="font-type:italic">That's easy</p>
%%        </body></html>
