Looks good! Did you put your code under an open source license so that it can be used without hesitation?
you can without hesitation. I'm not sure which license I put on it. But you
really don't have to worry about anything.
I hereby state that it is free for commercial use, non-commercial use,
open-source, not-open source, with or without source code. Free for
everything you like. Except for the creation of nuclear weapons and for
rocket launchers. :-)

Thanks for your response.
Ok, if you really want it that badly, I just won't use it for noclear weapons. 👍
