#D RULE: RunHistLife BeforeAfter
#D .
#D Simulates Conway' Life --  simultaneously showing an in situ shadow of the start state, and a
#D cumulative envelope of pattern history.
#D .
#D USAGE: Start Cells in State 5 (or 3). To run a regular life pattern, use the "Colors/Change State
#D of All Alive Cells" menu command and choose state 5. Cells started from state 1 will not leave a
#D shadow.
#D .
#D To rerun a sequence of generations, the starting and ending patterns can be interchanged
#D using the "Colors/Change State X to State Y" menu command. First change state 8 to state 5 to
#D reactivate the starting pattern. Then change state 1 to state 8 (shadow) or 2 (background) to
#D inactivate ending pattern. Blue background can be left in place without affecting new run.
#D .
#D COLORS: using standard 3-color palette: live cells = green or yellow; starting pattern shadow
#D cells = red or yellow; cells previously live but now dead = blue.
#D .
#D STATES:
#D state 1 = live cells
#D state 2 = dead cells previously alive = cumulative history
#D state 3 = alternative start state - equivalent to state 5
#D state 5 = live cells superimposed on shadow cells
#D state 8 = shadow cells = historical start cells
#D .
#D Credits: rule by Brice Due -- an extension of Dave Greene's HistoricalLife rule
