> A much faster than the naïve Levenshtein distance algoritme.
> This is an modified version of the Berghel Roach Levenshtein algortime
> with the time complexity of `O(n + d^2)` (n longest string, d edit distance).
> This is much faster compared to the naïve approach there uses `O(n*m)` (n and m are string lengths)
CPU time.

```javascript
var editdistance = require('editdistance');
var compare = editdistance('book');
console.log(compare.distance('back')); // 2
console.log(compare.distance('bounce')); // 4
