It should be noted that the ad XML that comes back from the ad server needs to be one of the supported Rich Media templates that Brightcove distributes for use with DFP and other ad serving platforms.
 * @param {String} pXML The XML string that gets returned from the ad server. Needs to be one of the templates supported by Brightcove.
 * @param {Object} pOptions An object that contains options for further customization. By default, this function will render the expanded banner (eg type: "expandedBanner") and also write out the banner to a div with the id of "expandedBanner" (eg writeTo: "expandedBanner"). For the type option, you can also choose "collapsedBanner". For the writeTo option, a user can specify the ID of any element they'd like.
