DPS Exclude Displayed Posts

If you’re using the Display Posts Shortcode multiple times in one page, or using it on a page with another loop of posts, use this to exclude already displayed posts from new shortcode queries.

Note: you’ll need to modify non-Display Posts Shortcode queries to add those post IDs to the global variable. This snippet is using a global variable found in the Genesis theme that already stores the list of displayed posts.
