To register a plant to be spawned at mapgen time rather than via an ABM, call
this function:
this function with two parameters: a table with the biome information, and
a string or table describing what to execute if the engine finds a suitable
node (see below):
plantslib:register_generate_plant(biome)
plantslib:register_generate_plant(biome, function_or_treedef)
Where "biome" is a table containing about a dozen variables:
biome = {
surface = "string", -- [*] what nodes to spawn on.
avoid = {table}, -- [*] what nodes to avoid when spawning.
radius = num, -- [*] how much distance to leave between
avoid_nodes = {table}, -- [*] what nodes to avoid when spawning.
avoid_radius = num, -- [*] how much distance to leave between
the object to be added and the objects
to be avoided.
seed_diff = num, -- perlin seed-diff value. Defaults to 0,

allowable temperature).
temp_max = num, -- maximum perlin temperature value (coldest
allowable temperature).
exec_funct = "string", -- [**] name of the function to use to
actually build the object if the code
decides it is time to do so.
}
[*] These entries are required for the spawn code to work. Everything else
is optional. Unless explicitly stated, all unused/unsupplied parameters
default to nil and will not affect the results of the code.
[**] A string indicating the name of the function that should be called if a
suitable spawn location has been found. This function will be passed a
single parameter, pos, indicating where the object should be placed.
Regarding function_or_treedef, this must either be a string indicating the
name of the function that should be called if a suitable spawn location has
been found, OR a table with an L-Systems tree definition.
If you specify a string with a function name, that function will be passed a
single position parameter (in the usual table format), indicating where the
object should be placed. If you specified an L-Systems tree definition, then
that definition will be passed directly to the spawn_tree() function along
with the position to spawn the tree on.
