Separate Session repository

[JoeBengalen]

Create wrapper class for the $_SESSION global that implements \ArrayAccess

Create ArrayAccessRepository which accepts both objects implementing ArrayAccess and real arrays.

Transform the SessionRepository to use the ArrayAccessRepository and SessionWrapper

Transform the ArrayRepository to use the ArrayAccessRepository

class Session implements ArrayAccess
{
    public function __construct()
    {
        $this->data = &$_SESSION;
    }

    public function isSessionActive()
    {
        return session_status() === PHP_SESSION_ACTIVE;
    }

    // ArrayAccess methods ...
}

class ArrayAccessRepository implements SimpleRepositoryInterface
{
    public function __construct(array $array)
    {
        $this->data = $array;
