Display Vendor-Submitted data as Restricted Content.

/**

 * This function demonstrates how to automatically display a field of content with the meta key 'my_prefix_restricted_content' (submitted 

 * through FES) to the content of the Product in question while wrapped in the edd_restrict shortcode.

 * Note: you can re-use this chunk for any field from your Submission form by swapping "my_prefix_restricted_content" with your field's custom meta_key.

 * An example of why you might use this: If you want to unlock/show a Vimeo/Youtube video only to customers who've purchased the product. 

 * For example, if you are setting up a video rental website, you could use this to display videos to customers after they purchase.

 *

 * To add a corresponding field to your Vendor Submission form, <br />

 * In EDD FES > Submission Form, add a field for the video URL with the meta_key set to "my_prefix_restricted_content".
