Title: compare string against a set of possible values

adds a function which compares a string against a set of possible values.
An example use case is when with the DS push API where both finishing and finished are valid states after calling the stop endpoint.
Usage

```php

$st->assertsString($response->body->status)->isIn(array("finishing", "finished"));

```
