* New: In Kite, in protectCagedTerminal(), check that the perpandicular
top METAL3 track is free before inserting the fixed protection.
They are added *after* the Pre-Routed stage and therefore we have
to check they do not cross.
* Change: In Kite, in NegociateWindow, print statistics before fixing
segment in the pre-routed stage to get correct results.
* Change, In CRL Core, in Measures when an addMeasure is performed
twice, let the new data erase the previous one (instead of keeping
the previous one).
