Message:

New global variables NumLanes, LaneQueuesSectIds, NumLaneQueuesSectIds, LaneQueueOffsets, LaneQueuesStatPos, LaneQueuesLaneIds, QueueLengthOffsets.
Corrected the computation of NumIntersections.
Added queue lengths to Drv and dt.
The step() methods fetches the last statistical data from Aimsun as well.
