 * This code allows your posts to have a fallback featured image based on your category. 
 * It requires manual upload of the featured images. In this case it assumed /category-images to have
 * been created in the root WP install directory.
 * It is based on this tutorial at WPBeginner:
 * http://www.wpbeginner.com/wp-themes/set-fallback-featured-image-based-post-category-wordpress/
 * The original tutorial assumed all categories have a featured image.
 * This codes inserts a div (to be styled) when there is also no featured image for the category.
 * Nathan Briggs was instrumental in implementation of the file_exists method.
