Usage:
Pass the entire output of any URL into the content of any page by adding [inlude_any_page url="example.com"]. Depending on the theme, a custom page template may be needed if you wish to wrap the external content in the site's header and footer.
Use the following as the page template in a new .php file, and add to your theme or child theme root:
<?php
/**
* Template Name: New Page Template Name
*/
?>
<?php get_header(); ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; ?>
<?php endif; ?>
<?php get_footer(); ?>
