* It is sometimes necessary to identify the link between assessmentItemRefs described in a QTI Test definition and the resources

* the assessmentItemRefs found in an AssessmentTest definition. The keys of the arrays are assessmentItemRef identifiers and
* values are IMS Manifest Resources.
*
* If an IMS Manifest Resource cannot be found for a given assessmentItemRef, the value in the returned array will be false.
*
* @param XmlDocument $test A QTI Test Definition.
* @param taoQtiTest_models_classes_ManifestParser $manifestParser A Manifest Parser.
* @param string $basePath The base path of the folder the IMS archive is exposed as a file system component.
* @return array An array containing two arrays (items and dependencies) where keys are identifiers and values are oat\taoQtiItem\model\qti\Resource objects or false.
