When new chunks are created, the calculated chunk hypercube might collide or not align with existing chunks when partitioning has changed in one or more dimensions. In such cases, the chunk should be cut to fit the alignment criteria and any collisions should be resolved. Unfortunately, alignment and collision detection wasn't properly handled. This refactoring adds proper axis-aligned bounding box collision detection generalized to N dimensions. It also correctly handles dimension alignment.
