#### Methods
* `get2d(pos)`: returns 2D noise value at `pos={x=,y=}`
* `get3d(pos)`: returns 3D noise value at `pos={x=,y=,z=}`
* `get_2d(pos)`: returns 2D noise value at `pos={x=,y=}`
* `get_3d(pos)`: returns 3D noise value at `pos={x=,y=,z=}`

#### Methods
* `get2dMap(pos)`: returns a `<size.x>` times `<size.y>` 2D array of 2D noise
* `get_2d_map(pos)`: returns a `<size.x>` times `<size.y>` 2D array of 2D noise
with values starting at `pos={x=,y=}`
* `get3dMap(pos)`: returns a `<size.x>` times `<size.y>` times `<size.z>` 3D array
* `get_3d_map(pos)`: returns a `<size.x>` times `<size.y>` times `<size.z>` 3D array
of 3D noise with values starting at `pos={x=,y=,z=}`
* `get2dMap_flat(pos, buffer)`: returns a flat `<size.x * size.y>` element array of 2D noise
* `get_2d_map_flat(pos, buffer)`: returns a flat `<size.x * size.y>` element array of 2D noise
with values starting at `pos={x=,y=}`
* `get3dMap_flat(pos, buffer)`: Same as `get2dMap_flat`, but 3D noise
* `calc2dMap(pos)`: Calculates the 2d noise map starting at `pos`. The result is stored internally.
* `calc3dMap(pos)`: Calculates the 3d noise map starting at `pos`. The result is stored internally.

* `calc_3d_map(pos)`: Calculates the 3d noise map starting at `pos`. The result is stored internally.
* `get_map_slice(slice_offset, slice_size, buffer)`: In the form of an array, returns a slice of the
most recently computed noise results. The result slice begins at coordinates `slice_offset` and
takes a chunk of `slice_size`.
E.g. to grab a 2-slice high horizontal 2d plane of noise starting at buffer offset y = 20:
`noisevals = noise:getMapSlice({y=20}, {y=2})`
`noisevals = noise:get_map_slice({y=20}, {y=2})`
It is important to note that `slice_offset` offset coordinates begin at 1, and are relative to
the starting position of the most recently calculated noise.
To grab a single vertical column of noise starting at map coordinates x = 1023, y=1000, z = 1000:
`noise:calc3dMap({x=1000, y=1000, z=1000})`
`noisevals = noise:getMapSlice({x=24, z=1}, {x=1, z=1})`
`noise:calc_3d_map({x=1000, y=1000, z=1000})`
`noisevals = noise:get_map_slice({x=24, z=1}, {x=1, z=1})`
