Tries to find intersections between a combination of arrays.

```
use Jelle_S\Util\Intersections\ArrayIntersections;

// Get all possible intersections, where the minimum array size of an
// intersection is 3.
$arrays = array(
 array(
   'a' => 1,
   'b' => 2,
   'c' => 3,
   'd' => 4,
   'e' => 9,
 ),
 array(
   'a' => 1,
   'b' => 2,
   'c' => 3,
   'e' => 9,
 ),
 array(
   'a' => 1,
   'b' => 42,
   'c' => 3,
   'd' => 4,

 ),
 array(
   'b' => 42,
   'c' => 3,
   'a' => 1,
 ),
 array(
   'z' => 26,
   'e' => 9,
   'a' => 1,
 ),
);
$intersections = new Jelle_S\Util\Intersections\ArrayIntersections($arrays, 3);
print_r($intersections->getAll());

print_r($intersections->getLargest());
```

Output:

```

            [e] => 9
        )

    [1] => Array
        (
            [a] => 1
            [c] => 3

        )

    [0] => Array
