This Javascript helper is actually also used internally by Umlaut to load background results as they come in.
*<b>NOTE*</b>: The intended use case at the moment is a "single item" or "item detail" page. You may think "Gee, I want to embed umlaut content for every item on a 10-item results page!" Handling this case isn't fully fleshed out yet, in part becuase it might put unreasonable load on an Umlaut server. But I have it in mind, and we may be able to get there, let jrochkind know if you demand it.
