Apply the [Levenshtein distance](https://en.wikipedia.org/wiki/Levenshtein_distance) to transform / morph an Array into another, performing the least amount of needed `.splice(...)` operations.

```js
const abra = ['a', 'b', 'r', 'a'];
majinbuu(abra, ['c', 'a', 'd', 'a', 'b', 'r', 'a']);

abra; // now ['c', 'a', 'd', 'a', 'b', 'r', 'a']
```

It is also possible to intercept all splice calls using an `aura`,
which augments the `splice` method of the list,
delegating the interceptor one.
```js
const abra = ['a', 'b', 'r', 'a'];
const interceptor = {
  splice(index, removal, ...items) {
    console.log(index, removal, ...items);
    abra.splice.apply(abra, arguments);
  }
};
const aura = majinbuu.aura(interceptor, abra);

majinbuu(aura, ['c', 'a', 'd', 'a', 'b', 'r', 'a']);
// 0 0 "c"
// 2 0 "d" "a"
```

The optional third argument avoid processing grids that are too big (comparing lists with too many items).
```js
const noMoreThan1K = 1000;
majinbuu(list1, list2, noMoreThan1K);
```
If the square of the `list1` and `list2` product is higher than `noMoreThan1K`,
the splice operation will remove all `list1` items and push all `list2`.

### Compatibility

Every. JavaScript. Engine.
