^ returns actual emerged pmin, actual emerged pmax
- write_to_map(): Writes the data loaded from the VoxelManip back to the map.
^ important: data must be set using VoxelManip:set_data before calling this
- get_node_at(pos): Returns a MapNode table of the node currently loaded in the VoxelManip at that position
- set_node_at(pos, node): Sets a specific MapNode in the VoxelManip at that position
- get_data(): Gets the data read into the VoxelManip object
^ returns raw node data is in the form of an array of node content ids
- set_data(data): Sets the data contents of the VoxelManip object
