+	dmm_suite version 1.0
+		Released January 30th, 2011.
+
+	NOTE: Map saving functionality removed
+
+	defines the object /dmm_suite
+		- Provides the proc load_map()
+			- Loads the specified map file onto the specified z-level.
+		- provides the proc write_map()
+			- Returns a text string of the map in dmm format
+				ready for output to a file.
+		- provides the proc save_map()
+			- Returns a .dmm file if map is saved
+			- Returns FALSE if map fails to save
+
+	The dmm_suite provides saving and loading of map files in BYOND's native DMM map
+	format. It approximates the map saving and loading processes of the Dream Maker
+	and Dream Seeker programs so as to allow editing, saving, and loading of maps at
+	runtime.
+
+	------------------------
+
+	To save a map at runtime, create an instance of /dmm_suite, and then call
+	write_map(), which accepts three arguments:
+		- A turf representing one corner of a three dimensional grid (Required).
+		- Another turf representing the other corner of the same grid (Required).
+		- Any, or a combination, of several bit flags (Optional, see documentation).
+
+	The order in which the turfs are supplied does not matter, the /dmm_writer will
+	determine the grid containing both, in much the same way as DM's block() function.
+	write_map() will then return a string representing the saved map in dmm format;
+	this string can then be saved to a file, or used for any other purose.
+
+	------------------------
+
+	To load a map at runtime, create an instance of /dmm_suite, and then call load_map(),
+	which accepts two arguments:
+		- A .dmm file to load (Required).
+		- A number representing the z-level on which to start loading the map (Optional).
+
+	The /dmm_suite will load the map file starting on the specified z-level. If no
+	z-level	was specified, world.maxz will be increased so as to fit the map. Note
+	that if you wish to load a map onto a z-level that already has objects on it,
+	you will have to handle the removal of those objects. Otherwise the new map will
+	simply load the new objects on top of the old ones.
+
+	Also note that all type paths specified in the .dmm file must exist in the world's
+	code, and that the /dmm_reader trusts that files to be loaded are in fact valid
+	.dmm files. Errors in the .dmm format will cause runtime errors.

+	SwapMaps library by Lummox JR
+	developed for digitalBYOND
+	http://www.digitalbyond.org
+
+	Version 2.1
+
+	The purpose of this library is to make it easy for authors to swap maps
+	in and out of their game using savefiles. Swapped-out maps can be
+	transferred between worlds for an MMORPG, sent to the client, etc.
+	This is facilitated by the use of a special datum and a global list.
+
+	Uses of swapmaps:
+
+	- Temporary battle arenas
+	- House interiors
+	- Individual custom player houses
+	- Virtually unlimited terrain
+	- Sharing maps between servers running different instances of the same game
+	- Loading and saving pieces of maps for reusable room templates
+ */
+
+/*
+	User Interface:
+
+	VARS:
+
+	swapmaps_iconcache
+		An associative list of icon files with names, like
+		'player.dmi' = "player"
+	swapmaps_mode
+		This must be set at runtime, like in world/New().
+
+		SWAPMAPS_SAV	0	(default)
+			Uses .sav files for raw /savefile output.
+		SWAPMAPS_TEXT	1
+			Uses .txt files via ExportText() and ImportText(). These maps
+			are easily editable and appear to take up less space in the
+			current version of BYOND.
+
+	PROCS:
+
+	SwapMaps_Find(id)
+		Find a map by its id
+	SwapMaps_Load(id)
+		Load a map by its id
+	SwapMaps_Save(id)
+		Save a map by its id (calls swapmap.Save())
+	SwapMaps_Unload(id)
+		Save and unload a map by its id (calls swapmap.Unload())
+	SwapMaps_Save_All()
+		Save all maps
+	SwapMaps_DeleteFile(id)
+		Delete a map file
+	SwapMaps_CreateFromTemplate(id)
+		Create a new map by loading another map to use as a template.
+		This map has id==src and will not be saved. To make it savable,
+			change id with swapmap.SetID(newid).
+	SwapMaps_LoadChunk(id,turf/locorner)
+		Load a swapmap as a "chunk", at a specific place. A new datum is
+		created but it's not added to the list of maps to save or unload.
+		The new datum can be safely deleted without affecting the turfs
+		it loaded. The purpose of this is to load a map file onto part of
+		another swapmap or an existing part of the world.
+		locorner is the corner turf with the lowest x,y,z values.
+	SwapMaps_SaveChunk(id,turf/corner1,turf/corner2)
+		Save a piece of the world as a "chunk". A new datum is created
+		for the chunk, but it can be deleted without destroying any turfs.
+		The chunk file can be reloaded as a swapmap all its own, or loaded
+		via SwapMaps_LoadChunk() to become part of another map.
+	SwapMaps_GetSize(id)
+		Return a list corresponding to the x,y,z sizes of a map file,
+		without loading the map.
+		Returns null if the map is not found.
+	SwapMaps_AddIconToCache(name,icon)
+		Cache an icon file by name for space-saving storage
+
+	swapmap.New(id,x,y,z)
+		Create a new map; specify id, width (x), height (y), and depth (z)
+		Default size is world.maxx,world.maxy,1
+
+	swapmap.New(id,turf1,turf2)
+		Create a new map; specify id and 2 corners
+		This becomes a /swapmap for one of the compiled-in maps, for easy saving.
+
+	swapmap.New()
+		Create a new map datum, but does not allocate space or assign an ID (used for loading).
+
+	swapmap.Del()
+		Deletes a map but does not save
+	swapmap.Save()
+		Saves to map_[id].sav
+		Maps with id==src are not saved.
+	swapmap.Unload()
