Using MaxInt instead of -1

[rodrigombsoares]

First of all, what an awesome lib! Thanks for the work. But I do have this design doubt:

Let's say I wanna compare strings two by two to a target using RankMatchNormalizedFold, for example:

s1 := "Hello Wor"
s2 := "Hello"
target := "hello world"
fmt.Println(fuzzy.RankMatchNormalizedFold(s1, target)) //2
fmt.Println(fuzzy.RankMatchNormalizedFold(s2, target)) //6

I could easily use math.Min(2,6) -> "Hello Wor" to find the best string in this case. But it would get me in trouble if any of the strings don't match, eg:

s1 := "foo"
s2 := "Hello"
target := "hello world"
fmt.Println(fuzzy.RankMatchNormalizedFold(s1, target)) //-1
fmt.Println(fuzzy.RankMatchNormalizedFold(s2, target)) //6

Where math.Min(-1,6) -> "foo"

Why using -1 instead of math.MaxInt if the lower the distance, the closer the strings?
