`Private` select

select(coord): [D, WangTile<D, unknown>]
Select an element via weighted random at the coordinates.
Parameters
- coord: D
  The coordinates to retrieve.
Returns [D, WangTile<D, unknown>]
the coordinate/tile pair that was set.
- Defined in packages/wang-tiles/src/lib/chunk.ts:77

`Private` findSmallestSet

findSmallestSet(): null | [D, WangTileSet<D, unknown>]
Find the smallest set in the coordinate map and return it, or null if no more sets exist.

Returns null | [D, WangTileSet<D, unknown>]
A coord/tileset pair or null

`Private` reduce

reduce(coord): V
Reduce the possibilities to a single tile.
Parameters
- coord: D
  The coordinate to retrieve.
Returns V
A single, randomly selected tile from the set.
