v0.2.14

• PATCH: new optional exports and fields, with no break: MemberRule.pool, PairGap, LayoutInput.pairGaps and canonicalInput. It also has a fix of generate.
• MemberRule.pool is a fixed list of member lists (L39). Each entry is a list of whole configs of the space of the members.
• With a pool, spaceSize counts each entry one time. enumerateSpace gives only entries of the pool, and checkConfig refuses another member list with the claim pool.
• checkSpace checks each entry of a pool. The shape filter of 0.2.13 also applies to the members of each entry. A rule without pool does not change.
• With a pool of 1 list on cell-portfolio, the meta count of packing at 3 levels goes from approximately 1.49e25 to approximately 1.72e15.
• LayoutInput.pairGaps gives a minimum distance to a pair of boxes (L49). For its pair, it replaces the two margins and the gap. PackInput and toPackInput carry it.
• checkInput refuses an unknown box, a pair of one box, a repeated pair in either order, a bad gap and bad lanes.
• The hard rule no-overlap reads pairGaps. For a pair of the list, in either order, the gap replaces the two margins. countOverlaps has a new optional third parameter pairGaps.
• A pair of the list breaks no-overlap only when the boxes are nearer than the gap on each axis. The other pairs keep their margins.
• canonicalInput sorts the pairs. documentHash uses it for each layout-input/1 document, so the order of the pairs does not change the hash.
• The fix: generate, resolve, cellOf and rngOf of a registry accept a cell of cellOf. They ignore a kind that is the familyKind of the family, and refuse another kind.
• Each input, verdict, record, hash and configId of 0.2.13 stays the same.
