FuzzySearch fails on empty string?

[amogh09]

Hey, kudos for the good work.

By the way, FuzzySearch fails on empty string input. I will look into your code and see if I can fix it.

package main

import "github.com/derekparker/trie"

func main() {
    t := trie.New()
    t.Add("foo", 1)
    t.FuzzySearch("")
}

Output -

panic: runtime error: index out of range
