Description
Corrected, refined and improved by Marco Binder (Heidelberg, Germany), 2025
using ChatGPT as a coding buddy. BUG FIXES: bug removed in tryAdd, where it was
implicitly expected that elements is never nil (which it was upon subdivision).
REFINEMENTS: improved efficiency in Box .contains(simd3_double), including using
an epsilon to prevent unneccessary subdivision upon rounding errors; several
other steps refined. IMPROVEMENTS: tree now autocollapses upon removing elements,
turning empty leafs into internal nodes again; accepts elements with box-regions
instead of point positions, similar to the Apple GKOctree implementation; now
respects minimumCellSize from initializer, saves it and subdivides only until
reaching minimum size, after which it bulks elements in single leave.
