+VoxelManip: An interface to the MapVoxelManipulator for Lua
+- Can be created via VoxelManip()
+- Also minetest.get_voxel_manip()
+methods:
+- read_chunk(p1, p2):  Read a chunk of map containing the region formed by p1 and p2.
+  ^ returns raw node data, actual emerged p1, actual emerged p2
+  ^ raw node data is in the form of a table mapping indicies to node content ids
+- write_chunk(data):  Write back the data 
+- update_map():  Update map after writing chunk.
+  ^ To be used only by VoxelManip objects created by the mod itself; not VoxelManips passed to callbacks
+- set_lighting(p1, p2, light):  Set the lighting in the region formed by p1 and p2 to light
+  ^ light is a table containing two integer fields ranging from 0 to 15, day and night
+  ^ To be used only by VoxelManip objects passed to a callback; otherwise, set lighting will be ignored
+- calc_lighting(p1, p2):  Calculate lighting in the region formed by p1 and p2
+  ^ To be used only by VoxelManip objects passed to a callback; otherwise, calculated lighting will be ignored
+- update_liquids():  Update liquid flow
