Testing only! Basic system capable of generating road patterns.
Complete rewrite of how groups, buildings, roads and metadata are handled by the mapgen
Complete rewrite of the structure ordering system. Roads and buildings can now spawn together without cutting into each other
Roads now detect and avoid self collision (cutting into each other)
Fix issues with collision detection and building placement
More code refractoring, new features, major fixes and improvements
Implement drawing of intersection shapes. The road system can now be considered ready
Allow structures to spawn in all 4 directions around other structures, for even more efficient space usage. Also fix road bounds and remove a now useless loop.
