A simple implementation of an N-dimensional fixed-size grid, implemented via a one-dimensional array lookup. Also contains basic N-dimensional vector logic to allow for lookups into (and enumeration through) those grids.
Can be hooked into virtually any game engine to provide a data structure for a grid of tiles. Particularly useful for voxel-based terrain implementation.
Documentation comments are desperately needed. I may add more to the vector math, as it currently does not support dot products or cross products.
