/*################################
File requesting this should have initialised the Ad Manager, and the relevant path should have been received in the 'adPathFromVelocity' variable:  

Eg: 
var adPathFromVelocityOrig = "$ad_a.getAdPath()"; 
//relative path to the random advertisment is returned by Velocity
var adPathFromVelocity = ((window.location.protocol).toString())+"//"+((window.location.host).toString())+"/qptcms"+adPathFromVelocityOrig; 
//Constructing the full path will help in the AJAX call.

The containers:
	<div class="productHomeAd"><div class="carouselContainer"> </div><div class="adCount"><ul></ul></div></div>

The path to the Ad Manger XML is also defined below, and can be changed if required - adManagerXMLPath


To add controls use the following in the base document (the class name to the anchor is the key):

<a href='javascript:;' class='controls play'>Play </a>
<a href='javascript:;' class='controls pause'> Pause</a>
<a href='javascript:;' class='controls first'>First </a>
<a href='javascript:;' class='controls next'>Next </a>
<a href='javascript:;' class='controls previous'> Previous</a>
<a href='javascript:;' class='controls last'>Last </a>
