Functions

func LevenshteinDistance

func LevenshteinDistance(a, b *string) int

func LevenshteinDistanceMax

func LevenshteinDistanceMax(a, b *string, max int) (int, bool)

levenshteinDistanceMax same as levenshteinDistance but attempts to bail early once we know the distance will be greater than max in which case the first return val will be the max and the second will be true, indicating max was exceeded
