- Change: Uses a map instead of a sorted vector in the layer assignment
steps. It was used to order GCells by density, and causing terrific
slowdown on big examples. Namely the eFPGA 16x16 took 1h20, now it's
down to 21 seconds...
Devellop a new object <DyKeyQueue> to handle map with elements
whose key *can* change. Next step is to normalize the key caching
mechanism and to templatize.
- Change: In LayerAssign, account the number of globals AutoSegments
moved up.
