  A loader for JSONP files, which are JSON-formatted text files, wrapped in a callback. To load regular JSON
  without a callback use the {{#crossLink "JSONLoader"}}{{/crossLink}} instead. To load JSON-formatted manifests,
  use {{#crossLink "ManifestLoader"}}{{/crossLink}}, and to load EaselJS SpriteSheets, use
  {{#crossLink "SpriteSheetLoader"}}{{/crossLink}}.
  
  JSONP is a format that provides a solution for loading JSON files cross-domain <em>without</em> requiring CORS.
  JSONP files are loaded as JavaScript, and the "callback" is executed once they are loaded. The callback in the
  JSONP must match the callback passed to the loadItem.
  
  <h4>Example JSONP</h4>
  
  callbackName({
  "name": "value",
  "num": 3,
  "obj": { "bool":true }
  });
  
  <h4>Example</h4>
  
  var loadItem = {id:"json", type:"jsonp", src:"http://server.com/text.json", callback:"callbackName"}
  var queue = new createjs.LoadQueue();
  queue.on("complete", handleComplete);
  queue.loadItem(loadItem);
  
  function handleComplete(event) }
  var json = queue.getResult("json");
  console.log(json.obj.bool); // true
  }
  
  Note that JSONP files loaded concurrently require a <em>unique</em> callback. To ensure JSONP files are loaded
  in order, either use the {{#crossLink "LoadQueue/setMaxConnections"}}{{/crossLink}} method (set to 1),
  or set {{#crossLink "LoadItem/maintainOrder:property"}}{{/crossLink}} on items with the same callback.
