-Rewrite of step 3b for accuracy - verified acceptable speed
--Can now detect an impossible balance situation and restart
-Eliminated false negatives in step 4 (still need to rework false positives)
-Minor key logic improvement
--Introduced reachable_switches
--Calculate total completion in equation resolution
--Prioritized one-way connections over neutral/neutral_profitable sectored but not over dead-ends
--Simplified finding good complex branching candidates - just re-used equations routine
--Valid multi choice for global polarity when fixing parity
--Added total dungeon charge as critieria when fixing parity
--Pinball used for navigation in skull 2, marked appropriately (particularly with Ice Cross in Skull 2)
--Equation resolution detects used benefits with unreached_doors benefits
--Greedy equation finder not longer used destination/entrance sectors of the wrong split dungeon
--Required connections don't overestimate benefits
--Introduced the concept of crystal switches and doors blocked by blue barriers to equations
New algorithm also obsoletes sweep_for_crystal_access
Set up door and entrance caches in advance
Replace CrystalBarrier with FastEnum for bitfield arithmetic
For OWG, allow superbunny in superbunny cave with no mirror when entering from the bottom
Fix boots clip logic to desert teleporter ledge and TR teleporter
Fix mirror wrap logic for pyramid fairy
For insanity shuffle, exiting Superbunny Cave bottom is now in logic.
--PoD Vanilla Stairway
--Boss should not be allowed key
--Scale back on aggressive layouts
Merge of attic hint
Non-chest keys hints added for figuring out how to get rid of them
Better batching support for mass testing of seed generation.
Generation issues fixed:
--Filler now tests with the key in the proposed location to enable alternate key rules
--Key rule checker now only considers key locations that the parent sphere did not have - better key rules
