-- Dates growing functions.
-- This is a bit complex, as the purpose is to find male flowers at horizontal distances of over
-- 100 nodes. As searching such a large area is time consuming, this is optimized in four ways:
-- - The search result (the locations of male trees) is cached, so that it can be used again
-- - Only 1/9th of the desired area is searched at a time. A new search is only performed if no male
-- flowers are found in the previously searched parts.
-- - Search results are shared with other female palms nearby.
-- - If previous searches for male palms have consumed too much CPU time, the search is skipped
-- (This means no male palms will be found, and the pollination of the flowers affected will be
-- delayed. If this happens repeatedly, eventually, the female flowers will wither...)
-- A caching method was selected that is suited for the case where most date trees are long-lived,
-- and where the number of trees nearby is limited:
-- - Locations of male palms are stored as metadata for every female palm. This means that a player
-- visiting a remote area with some date palms will not cause extensive searches for male palms as
-- long overdue blossoming ABMs are triggered for every date palm.
-- - Even when male palms *are* cut down, a cache refill will only be performed if the cached results do not
-- contain a male palm with blossoms.
-- The method will probably perform suboptimally:
-- - If female palms are frequently chopped down and replanted.
-- Freshly grown palms will need to search for male palms again
-- (this is mitigated by the long blossoming interval, which increases the chance that search
-- results have already been shared)
-- - If an area contains a large number of male and female palms.
-- In this area, every female palm will have an almost identical list of male palm locations
-- as metadata.
-- - If all male palms within range of a number of female palms have been chopped down (with possibly
-- new ones planted). Although an attempt was made to share search results in this case as well,
-- a number of similar searches will unavoidably be performed by the different female palms.
-- - If no male palms are in range of a female palm. In that case, there will be frequent searches
-- for newly-grown male palms.
-- Search statistics - used to limit the search load.
