Module for handling async ad rendering on Cars.com (given a document.write implementation for DFP or other ad serving platforms). Leverages modified Postscribe and htmlParser libraries (modified to work via AMD). Registers full event system for rending ads globally, specifically, or in new elements. Updates targeting each load via server for any state changes. Maintains targeting cache for all ad locations on a given page. Identifies newly generated ad-slots created after page load. Hooks for caching data on client. Manages all custom logic for ad call generation internally; maintains consistency over any given number of ad renders.
