+/// A struct representing the data used to procedurally generate a maze with the
+/// "Hauberk" algorithm by Bob Nystrom described at
+/// https://journal.stuffwithstuff.com/2014/12/21/rooms-and-mazes/ and
+/// implemented in https://github.com/munificent/hauberk/ in Dart, with
+/// inspiration from the pre-existing rust implementation implemented in
+/// https://github.com/graysentinel/roguelike-rust/.
+///
+/// ## Details
+///
+/// When the mazegen mapmanip runs, it first marks out all the tiles it can
+/// modify by checking to see if they have an area set to the `allowed_area`
+/// setting. It scales the map down to a grid at 1/3rd size, and performs the
+/// mazegen largely as described in Nystrom's post. It uses the passed in
+/// `room_configs` as a list of possible room sizes and quantities to attempt to
+/// spawn.
+///
+/// Once complete, each cell in the grid is converted to hallways and floors. If
+/// the mapmanip finds a "straight" vertical or horizontal hallway comprised of
+/// hallway cells along one axis, surrounded by wall cells, either the
+/// `hallway_horizontal_marker` or `hallway_vertical_marker` submap markers are
+/// inserted at the bottom left of the 3x3 area around the center cell being
+/// checked. This means that the horizontal and vertical hallway markers are
+/// given a 9x9 in-game tile area to work with, despite the hallway being either
+/// 3x9 or 9x3. This gives mappers some leeway to expand the hallways a column
+/// or row on either side, so long as they remain cognizant that these submap
+/// insertions may overlap. For example, if you have two vertical hallway
+/// markers, one right next to the other, the one on the left will share a 3x9
+/// column of in-game turfs with the one on the right. As long as these submaps
+/// do not extend too far out to each other, they can be cleverly used to expand
+/// the areas that hallways take up.
+///
+/// The `hallway_node_marker` submap marker is used for nearly all hallway cells
+/// that do not meet the above criteria for being part of a "straight" vertical
+/// or horizontal hallway. This submap should be 3x3 tiles, and not anticipate
+/// walls being on any of its sides.
+///
+/// ## JSON Config
+///
+/// A sample mapmanip configuration may look like this:
+///
+/// ```json
+/// {
+///     "type": "MazegenHauberk",
+///     "allowed_area": "/area/mazegen",
+///     "default_floor": "/turf/simulated/floor/plasteel",
+///     "winding_percent": 20,
+///     "extra_connector_chance": 20,
+///     "hallway_horizontal_marker": "/obj/effect/map_effect/marker/mapmanip/submap/insert/deepmaints/hallway_horizontal",
+///     "hallway_vertical_marker": "/obj/effect/map_effect/marker/mapmanip/submap/insert/deepmaints/hallway_vertical",
+///     "hallway_node_marker": "/obj/effect/map_effect/marker/mapmanip/submap/insert/deepmaints/hallway_floor",
+///     "room_configs": [
+///         {
+///             "marker": "/obj/effect/map_effect/marker/mapmanip/submap/insert/deepmaints/small",
+///             "width": 3,
+///             "height": 3,
+///             "min": 7,
+///             "max": 9
+///         },
+///         {
+///             "marker": "/obj/effect/map_effect/marker/mapmanip/submap/insert/deepmaints/medium",
+///             "width": 5,
+///             "height": 5,
+///             "min": 2,
+///             "max": 3
+///         }
+///     ]
+/// }
+/// ```
+///
+/// ## Shortcomings
+///
+/// 1. Currently this mapmanip only works on the 1st z-level of a map file. This
+///    isn't an impossible thing to fix, I just didn't feel like setting it up
+///    to handle other z-levels.
+/// 2. As a result of the mazegen algorithm using odd-sized rooms to ensure
+///    consistent spacing for hallways and junctions, and the fact that the maze
+///    is generated on a grid scaled to 1/3rd the original map size, all rooms
+///    must have sides with dimensions that are both odd and multiples of three,
+///    e.g. 9, 15, 21.
