 *
 *  The purpose of this file is to create the front-end AJAX logic for the new
 *   news center.
 *
 *         Usage: populateListing([CONTENT-TYPE],[LISTING-ID],[LIST-SIZE],[LIST-TYPE])
 *  Requirements:
 *         [CONTENT-TYPE]:
 *            "releases"    - Press Releases
 *            "articles"    - External News Articles (Wrappers)
 *            "clients"     - Client Pages
 *            "partners"    - Partner Pages
 *            "events"      - Event Pages
 *            "resources"   - Resources (Wrappers)
 *         [LISTING-ID] (int)
 *            The CMS ID of the listing page (for uniqueness and access)
 *         [LISTING-SIZE] (int)
 *            The number of elements to be returned in this listing.
 *         [LIST-TYPE] must be:
 *            "links"       - Only links are listed (text is the title of the element)
 *            "details"     - HTML list is produced with full detail for each element
 *            "summary"     - Simple line-separated entries are produced with title-link and summary only
