Binary counter

LCAU41.C in particular, contains enhanced rule and line editing menus which allow experimentation with the design of rules. Certain of the demonstrations in show how the design process can be used. There is an example of a ``binary counter'' which consists of a glider gun together with bistable targets. In one state the target absorbs the glider and changes to the other state. In the second state the target passes the glider, reverting to the first state. Thus half the gliders are lost to each target, whose state forms a binary counter whose carry is represented by the gliders which are allowed to pass.
