# Note: The idea behind this experiment is to use Command Blocks 
# (RUINSTRIGGER and /testruin) to get around the Ruins Mod
# build-point spawning rules, so underground features can
# be added without requiring that the surface area be "leveled"
# to maximize spawn chances (based on observation that structures
# with large footprints have difficulty spawning in hilly areas
# without use of "max_leveling").  This "seed" structure has a
# pretty small footprint (1x1) so it has a decent chance of
# finding a valid build point.  When it invokes /testruin to
# summon a random underground structure, that structure won't be
# subjected to further build-point testing.
