Collections Abstraction library

## Changelog

### v1.3.0

* [Explicit casting of first and max results in criteria API](https://github.com/doctrine/collections/pull/26)
* [Keep keys when using `ArrayCollection#matching()` with sorting](https://github.com/doctrine/collections/pull/49)
* [Made `AbstractLazyCollection#$initialized` protected for extensibility](https://github.com/doctrine/collections/pull/52)

### v1.2.0

* Add a new ``AbstractLazyCollection``

### v1.1.0

* Deprecated ``Comparison::IS``, because it's only there for SQL semantics.
  These are fixed in the ORM instead.
* Add ``Comparison::CONTAINS`` to perform partial string matches:

        $criteria->andWhere($criteria->expr()->contains('property', 'Foo'));
