### What it does
Checks for use of `.skip(x).next()` on iterators.

### Why is this bad?
`.nth(x)` is cleaner

### Example
```
let some_vec = vec![0, 1, 2, 3];
let bad_vec = some_vec.iter().skip(3).next();
let bad_slice = &some_vec[..].iter().skip(3).next();
```
The correct use would be:
```
let some_vec = vec![0, 1, 2, 3];
let bad_vec = some_vec.iter().nth(3);
let bad_slice = &some_vec[..].iter().nth(3);
```
