Map

Rules:
1) In the SPUD thread, make an edit to the map by specifying coordinates (XYZ format, see rule 2 for more details) and a number from 0-9 (see rules 3 and 4), or X (see rule 7).
2): X is left-right, from 0 to n. So X = 0 refers to the leftmost line of a layer.
	Y is up-down (on page), from 0 to n. So Y = 0 refers to the topmost line of a layer.
	Z is down-up (in map), from 0 to n. So Z = 0 refers to the topmost layer on the page, but the bottommost layer of the map.
3) A region of neighbouring identical numbers is a single map section, this map section is later to be created by someone.
4) If two map sections have numbers that have a difference greater than one, the border between them is blocked. Otherwise, it is open.
5) Blocked borders have culled outer faces. Culled faces are ignored in a lot of calculations, which is important for efficiency.
6) If a map section is touching the map border, it will be nothing but empty space. Anything that would usually be an opening into it is instead skybox.
7) X is also nothing but empty space, but what the border is is entirely up to the creator of the map section opposite the border. Any blocked parts of the border cannot have culled outer faces. Overidden by the previous rule.
8) Each number refers to a 512x512x512 HU cube (512 HU is 32 feet).

Here's the map! Remember, the top grid is layer 0, the bottom layer of the map.
