+ * ProductAdvertisingAPI 5.0 NodeJS SDK.<br>
+ * The <code>index</code> module provides access to constructors for all the classes which comprise the public API.
+ * <p>
+ * An AMD (recommended!) or CommonJS application will generally do something equivalent to the following:
+ * <pre>
+ * var ProductAdvertisingAPIv1 = require('index'); // See note below*.
+ * var xxxSvc = new ProductAdvertisingAPIv1.XxxApi(); // Allocate the API class we're going to use.
+ * var yyyModel = new ProductAdvertisingAPIv1.Yyy(); // Construct a model instance.
+ * yyyModel.someProperty = 'someValue';
+ * ...
+ * var zzz = xxxSvc.doSomething(yyyModel); // Invoke the service.
+ * ...
+ * </pre>
+ * <em>*NOTE: For a top-level AMD script, use require(['index'], function(){...})
+ * and put the application logic within the callback function.</em>
+ * </p>
+ * <p>
+ * A non-AMD browser application (discouraged) might do something like this:
+ * <pre>
+ * var xxxSvc = new ProductAdvertisingAPIv1.XxxApi(); // Allocate the API class we're going to use.
+ * var yyy = new ProductAdvertisingAPIv1.Yyy(); // Construct a model instance.
