Common framework [for cellular automaton rules]

The Mathematica built-in function CellularAutomaton discussed on page 867 handles general and totalistic rules in the same framework by using ListConvolve[w, a, r+1] and taking the weights w to be respectively k^Table[i-1, {i, 2r+1}] and Table[1, {2r+1}].
