Experimental flow field pathfinding Kind of got flow field generation down to a minor stutter... Struct test - slower (50%) Much faster Chunked Flow Field with "portal" connections coming soon(TM) Backup So close to having working flow field that's reasonably fast, except sometimes units get stuck alternating between nodes Various improvements and optimizations but units still get stuck between portals Backup WIP Fully functional flow field pathfinding with chunks / HPA* Removed debug line and set hard map limit of 30k x 30k The flow field pathfinding is now better and units can correctly approach buildings again. The flow field will update automatically when new buildings are created. Merge branch 'flowfields'
