Helps to avoid problems caused by 'chunk-in-shell' feature of mapgen.cpp.
It also queues your generators to run them in proper order:
## mcl_mapgen.register_chunk_generator(chunk_callback_function, priority)
=========================================================================
Registers callback function to be called when current chunk generation is finished.
`callback_function`: chunk callback function definition:
`function(minp, maxp, seed)`:
`minp` & `maxp`: minimum and maximum chunk position;
`seed`: seed of this mapchunk;
`priority` (optional): order number - the less, the earlier,
e.g. `mcl_mapgen.priorities.BUILDINGS` or `mcl_mapgen.priorities.LARGE_BUILDINGS`
## mcl_mapgen.register_block_generator(callback_function, priority)
===================================================================
Registers callback function to be called when block (usually 16x16x16 nodes) generation is finished.
`callback_function`: block callback function definition, see below;
`priority` (optional): order number - the less, the earlier,
e.g. `mcl_mapgen.priorities.BUILDINGS` or `mcl_mapgen.priorities.LARGE_BUILDINGS`
## mcl_mapgen.register_block_generator_lvm(callback_function, priority)
=======================================================================
Registers callback function to be called when block (usually 16x16x16 nodes) generation is finished.
`vm_context` passes into callback function and should be returned back.

=======================================================================
UNSAFE! See https://git.minetest.land/MineClone2/MineClone2/issues/1395
Registers callback function to be called when current chunk generation is finished.
IT IS UNSAFE! GROUND CONTENT YOU PLACE (INCLUDING WATER AND AIR) CAN BE OVERWRITTEN BY cavegen.
ALL OTHER API FUNCTIONS ARE SAFE! USE THEM PLEASE! BUT WE NEED THIS FUNCTION STILL SOMETIMES,
WHEN WE NEED TO ACCESS MAPGEN OBJECTS like `heightmap`, `biomemap`, ETC.
`callback_function`: chunk callback LVM function definition, see below;
### mcl_mapgen.register_on_generated(callback_function, order_number)
For Minetest 5.4 it doesn't recommended to place blocks within callback function.
See https://git.minetest.land/MineClone2/MineClone2/issues/1395
`callback_function`: chunk callback LVM function definition:
`function(vm_context)`:
Function MUST RETURN `vm_context` back anyway! It will passed into next callback function from the queue.
`vm_context`: a table which already contains some LVM data if the fields, and some of them can be added right in callback function:
`vm_context`: a table which already contains some LVM data if the fields, and some of them can be added by you right in the callback function:
`vm`: curent voxel manipulator object itself;
`blockseed`: seed of this mapchunk;
`minp` & `maxp`: minimum and maximum chunk position;

Returns node if it is generated. Otherwise returns `{name = "ignore"}`.
## Constants:
* `mcl_mapgen.EDGE_MIN`, `mcl_mapgen.EDGE_MAX` - world edges, min & max.
* `mcl_mapgen.seed`, `mcl_mapgen.name` - mapgen seed & name.
* `mcl_mapgen.v6`, `mcl_mapgen.superflat`, `mcl_mapgen.singlenode` - is mapgen v6, superflat, singlenode.
* `mcl_mapgen.normal` is mapgen normal (not superflat or singlenode).
