rule converter
Sometimes you find in literature or in programs
(mostly in "Game of Life" themes) rules in notation like 23/3 or S23/B3
or similar. S means stable and B Birth. This says for the
Moore-neighbourhood 
, that for the next generation the cell with 2 living (state = 1)
neighbours is stable and with 3 living neighbours the cell is still
living or born. This is the rule of the "Game of Life".
But GeZA2D is using a new Kind of ruling convention. For converting
rules from the old notation into the new GeZA like, this little tool
helps you.
Click on the buttons (0..8) right from the S (stable) or B (Birth) to activate or deactivate them.
After "old Style" you'll find the rule in conventional notation and beneath "GeZA rule" the notation using this app.
Clicking on the button "use it" will go back to the option dialog with the new defined rule.
If the current rule is not valid for 'old style'-notation, the 'game of life' rule is preset!
