Cauldron2D.Grid.Coarse.Regions (Cauldron2D v0.2.2)

The regions of a grid for Cauldron2D.Grid.Coarse: within each block of block tiles a side, the open tiles joined edge to edge, numbered from 1.

:labels — a binary of one 32-bit region number for each tile, row by row, 0 for a tile that is not open
:count — how many regions there are
:spots — a tuple, the region numbered n at index n - 1, of the region's tile nearest its middle
:links — a tuple in the same order of [{region, cost}], the regions a region touches edge to edge across a block border, the cost the distance between spots
:components — a tuple in the same order of the number shared by every region that can reach every other
