rule editor

Touching on the rule string in the option dialog, this rule editor will be opened.


You see the rule string on the top. Touching on this string sets the cursor. The number in red among them shows the current cursor/string position. This is useful, cause the character at this position dictates the value of the cell in the next generation, if the sum of the neighbour cells values is equal to the position number.
Touch the button "use it" and provides the new rule to the option dialog and  goes back.

There is a problem with rules longer than display width. I'm working on it.
