* Determines if a post, identified by the specified ID, exist
* within the WordPress database.
*
* Note that this function uses the 'acme_' prefix to serve as an
* example for how to use the function within a theme. If this were
* to be within a class, then the prefix would not be necessary.
*
* @param int $id The ID of the post to check
* @return bool True if the post exists; otherwise, false.
