The initial implementation of the code stored squares in the grid in a "pretty" form. This is a complicated bit of code and slowed down the code slightly. Now we just store the size of the current square in the grid. This reduces the code complexity, and offers a slight performance improvement. We still output a prettified version of the grid, as we can generate that from a grid populated with just square sizes.
