pre-compute and cache possible purviews,
fix bipartition function,
add parallel constellation functionality,
concept distance over least-common-purview rather than whole system,
one-element cut approximation,
MICE caching,
relevant_connections on MICE objects for cache check,
only recheck concepts and cut mechanisms after system cut.
