# For part 1, we were limited to an area of -50..50 for all three directions.
# For part 2, this limitation is no longer in place. That means we cannot keep
# track of all the points individually. Instead, it will be necessary. To keep
# track of regions. Ultimately, we then have to perform arithmetic on the
# regions. This is not trivial enough for me right now.
