// We will store the data for the MiddMedia files in the post in a global array that
// we will reference later when rendering the RSS feed via our 'rss2_item' action hook
// that calls our middmedia_add_enclosures() function.
//
// The other way to accomplish this result would be to add a custom field to the post
// called 'enclosure' (that contains this data) at the time the post is saved. The downside
// of that approach however is that updates to the media (such as URL or size changes)
// would not be automatically passed through to the feed. This approach keeps that data
// out of the WordPress database.
