+/**
+ * <p>Provides a JSONPRequest class for repeated JSONP calls, and a convenience
+ * method Y.jsonp(url, callback) to instantiate and send a JSONP request.</p>
+ *
+ * <p>Both the constructor as well as the convenience function take two
+ * parameters: a url string and a callback.</p>
+ *
+ * <p>The url provided must include the placeholder string
+ * "{callback}" which will be replaced by a dynamically
+ * generated routing function to pass the data to your callback function.
+ * An example url might look like
+ * "http://example.com/service?callback={callback}".</p>
+ *
+ * <p>The second parameter can be a callback function that accepts the JSON
+ * payload as its argument, or a configuration object supporting the keys:</p>
+ * <ul>
+ * <li>on - map of callback subscribers
+ * <ul>
+ * <li>success - function handler for successful transmission</li>
+ * <li>failure - function handler for failed transmission</li>
+ * <li>timeout - function handler for transactions that timeout</li>
+ * </ul>
+ * </li>
+ * <li>format - override function for inserting the proxy name in the url</li>
+ * <li>timeout - the number of milliseconds to wait before giving up</li>
+ * <li>context - becomes <code>this</code> in the callbacks</li>
+ * <li>args - array of subsequent parameters to pass to the callbacks</li>
+ * <li>allowCache - use the same proxy name for all requests? (boolean)</li>
+ * </ul>
