+This is the start of a high performant c++ Wave Function Collapse repo for n-dimensions. To increase performance we want to avoid using a large memory footprint, virtual polymoprhism, etc.
+
+For now we want to make it possible to use and test WFC with 2 dimensions, but later on we'll want to use 3D or even 4D. Please implement the algorithm with 2 dimensions for now. use the console for outputting tests.
