The inner-loop draws each tile to fill out a row, after which the turtle goes

back to the beginning of the row and then moves up to begin filling out the

next row (the outer-loop controls how many times to shift up in the overall

grid), continuing this build-row-then-shift process until the complete

grid has been created. The turtle finishes the process back in the lower-left

corner of the grid that it created.
