/**
* Load a collection of xPDOObject instances and a graph of related objects.
*
* @static

* @param string|array $graph A related object graph in array or JSON
* format, e.g. array('relationAlias'=>array('subRelationAlias'=>array()))

* are necessary in order for the relation to be recognized.
* @param mixed $criteria A valid primary key, criteria array, or xPDOCriteria instance.
* @param boolean|integer $cacheFlag Indicates if the objects should be
* cached and optionally, by specifying an integer value, for how many
* seconds.
* @return array An array of xPDOObject instances or an empty array if no instances are loaded.
