Since the code has two arrays of the area before and after,
the copy order is totally irrelevant.
Of course, this doesn't apply to metadata and we still need
to do that backwards.
Non-stylistic changes:
* Add LuaDoc/LDoc support.
* Fix `clear_objects` area size calculation.
* Fix `clear_objects` removing player objects.
* Fix shadowing of marker entity name with player name.
* Make visualization functions use `swap_node`.
* Make hidden nodes unwalkable.
* Prevent `hide` from hiding air.
* Make deprecated functions log to deprecated stream when called.
* Fixed `replaceinverse` not using normalized node names.
* Added .gitignore.
* Bump version to 1.1.
Stylistic changes:
* Change `x = function` to `function x`.
* Change comment format.
* Make missing VoxelManip error less obnoxious.
* Move `sort_pos` into `common.lua`, which is a required module.
* Remove local copies of `minetest`.
* Remove `worldedit = worldedit or {}` from modules.
* Replace replaceinverse with an inverse argument to `replace`.
* Added `error()`s on on invalid axes.
* Change `wip` to `TODO`.
* Rename `clearobjects` to `clear_objects`.
* Remove `hollow_{sphere,dome,cylinder}` and replace them with a hollow parameter to each function.
* Add helpers to reduce code duplication.
* Renamed `Chat Commands.md` to `ChatCommands.md`.
* Adds a header to serialized data (to make version checking sane).
* Removes the duplicate deserialization for `worldedit.deserialize` and `worldedit.allocate`.
* Optimizes `worldedit.deserialize` by only deserializing the data once.
* Makes some fields optional.
* Cleans up the comments and a little of the code style.
Continuation Passing Style lets me use minetest.after, so the server
gets a chance to not hang in between every stack iteration. Could even
set minetest.after(1000,nextone) if you want to see it extend once every
second.
