* New: In AnabaticEngine::printMeasures(), re-enable runtime & memory
footprint in measurements.
* Bug: In Anabatic::AutoSegment CTOR, correct computation of the initial
number of global segments. We were relying on the "global" flag,
which is *not* set at this stage. Now compare source and target
GCells.
* New: In KatanaEngine::runGlobalRouter(), store H-ovE & V-ovE in
measurements.
* New: In KatanaEngine CTOR, add the number of gates (flattened) to
the measurments.
* New: In KatanaEngine::runNegociate(), add the number of GCells to
the measurements.
* Change: In KatanaEngine::printCompletion(), compute the wirelengths
in either lambdas (symbolic) or *nanometers* (real).
* New: In cumulus/plugins.block.Block, add a setting to request the
Katana measurements dumping: "cfg.katana.dumpMeasures"
