calling getItems() on ArrayType instance throws exception

[imissyouso]

Expected Behavior

Method getItems() on ArrayType instance should return any object of TypeInterface
For example for RAML spec like:

...
types:
  Cats:
    type: object[]
    items:
      properties:
        name: string
...

call:

foreach ($apiDef->getTypes() as $type) {
    var_dump($type->getItems());
}

should print dump of StringType object

Actual Behavior

Throws exception:

Exception: No type found for name array 

because

    /**
     * Retrieves a type by name
     *
     * @param string $name Name of the Type to retrieve.
     *
     * @return \Raml\TypeInterface Returns Type matching given name if found.
     * @throws \Exception When no type is found.
     **/
    public function getTypeByName($name)
    {
        foreach ($this->collection as $type) {
            /** @var $type \Raml\TypeInterface */
            if ($type->getName() === $name) {
                return $type;
            }
        }
        throw new \Exception(sprintf('No type found for name %s, list: %s', var_export($name, true), var_export($this->collection, true)));
    }

it tries to find the array type inside the list of already declared complex types instead of create new scalar StringType

similar behaviour is actual for:

types:
  Cat:
    type: object
    properties:
      owner: Person
      name: string

Pls direct me how to work with such structures? How to get access to owner field? If lib doesn't support structures like this pls assign me to this issue and I'll start working on it :)
