Kite is now deterministic, given a global routing.
* Bug: In Kite, in TrackCost, the boolean attribute "_forGlobal" was not initialized in the constructor causing the non-deterministic behavior. Arrrrgggghhhhhh. * Bug: In Kite, in PyKiteEngine, forgot to perform the "balanceGlobalDensity()" in the layer assign Python wrapper, another cause for non-determinism. * Change: In Kite, In KiteEngine, print the configuration at the same point as in the python script (to get identical output).
