Sort typeahead suggestions with the exact input at top

To sort all matches by closeness to the input, you can take the Levenshtein distance of a and b. I just implemented this using fast-levenshtein and it works and performs great.

        sorter: function(a, b) {
            var input_string = $(selector).val();
            return levenshtein.get(a.key, input_string) - levenshtein.get(b.key, input_string);
        }
