docs: constructor 
  A loader for JSON manifests. Items inside the manifest are loaded before the loader completes. To load manifests
  using JSONP, specify a {{#crossLink "LoadItem/callback:property"}}{{/crossLink}} as part of the
  {{#crossLink "LoadItem"}}{{/crossLink}}.
  
  The list of files in the manifest must be defined on the top-level JSON object in a `manifest` property. This
  example shows a sample manifest definition, as well as how to to include a sub-manifest.
  
  {
  "path": "assets/",
  "manifest": [
  "image.png",
  {"src": "image2.png", "id":"image2"},
  {"src": "sub-manifest.json", "type":"manifest", "callback":"jsonCallback"}
  ]
  }
  
  When a ManifestLoader has completed loading, the parent loader (usually a {{#crossLink "LoadQueue"}}{{/crossLink}},
  but could also be another ManifestLoader) will inherit all the loaded items, so you can access them directly.
  
  Note that the {{#crossLink "JSONLoader"}}{{/crossLink}} and {{#crossLink "JSONPLoader"}}{{/crossLink}} are
  higher priority loaders, so manifests <strong>must</strong> set the {{#crossLink "LoadItem"}}{{/crossLink}}
  {{#crossLink "LoadItem/type:property"}}{{/crossLink}} property to {{#crossLink "AbstractLoader/MANIFEST:property"}}{{/crossLink}}.
