Creates a question from a QTI file.

Receives parameters from a QTI parser and creates a valid ILIAS question object

Parameters:
object $item The QTI item object
integer $questionpool_id The id of the parent questionpool
integer $tst_id The id of the parent test if the question is part of a test
object $tst_object A reference to the parent test object
integer $question_counter A reference to a question counter to count the questions of an imported question pool
array $import_mapping An array containing references to included ILIAS objects public

Reimplemented from assQuestionImport.
