WorldEdit API
-------------
=============
The WorldEdit API is composed of multiple modules, each of which is independent and can be used without the other. Each module is contained within a single file.
For more information, see the [README](README.md).
Manipulations
-------------
Contained in manipulations.lua, this module allows several node operations to be applied over a region.
### worldedit.volume(pos1, pos2)
Determines the volume of the region defined by positions `pos1` and `pos2`.

Returns the number of nodes replaced.
### worldedit.hollow_sphere = function(pos, radius, nodename)
Adds a hollow sphere at `pos` with radius `radius`, composed of `nodename`.
Returns the number of nodes added.
### worldedit.sphere = function(pos, radius, nodename)
Adds a sphere at `pos` with radius `radius`, composed of `nodename`.
Returns the number of nodes added.
### worldedit.hollow_cylinder(pos, axis, length, radius, nodename)
Adds a hollow cylinder at `pos` along the `axis` axis ("x" or "y" or "z") with length `length` and radius `radius`, composed of `nodename`.
Returns the number of nodes added.
### worldedit.cylinder(pos, axis, length, radius, nodename)

Primitives
----------
Contained in primitives.lua, this module allows the creation of several geometric primitives.

Visualization
-------------
Contained in visualization.lua, this module allows nodes to be visualized in different ways.
### worldedit.hide(pos1, pos2)
Hides all nodes in a region defined by positions `pos1` and `pos2` by non-destructively replacing them with invisible nodes.
Returns the number of nodes hidden.
### worldedit.suppress(pos1, pos2, nodename)
Suppresses all instances of `nodename` in a region defined by positions `pos1` and `pos2` by non-destructively replacing them with invisible nodes.

Restores all nodes hidden with WorldEdit functions in a region defined by positions `pos1` and `pos2`.
Returns the number of nodes restored.
Serialization
-------------
Contained in serialization.lua, this module allows regions of nodes to be serialized and deserialized to formats suitable for use outside MineTest.
### worldedit.serialize(pos1, pos2)
Converts the region defined by positions `pos1` and `pos2` into a single string.
