How to traverse a CellularSpace
-- simulating rain in a certain region
ForEachCell(
myCellSpace,
function(i,cell)
cell.soilWater = cell.past.soilWater + 2
return true
end

ForEachCell(cs, function(i, cell)...end)
Change trajectories: stamping spatial
patterns of change

Spatial iterators: are modeller defined functions which
maps indexes (atributtes) to geo-objects (cells).
