Add a slider for the strictness of the answer checker (manipulate the maximum Levenstein Distance)

That way you can decide how much you want to challenge yourself to have an accurate answer, or just go for "close enough" (which can be advantageous for hard to spell answerlines)

The relevant changes would be in the answer checker repo, specifically around here:
