New definition of complex type

The exposure of complex type properties was done only with public property.
Now you can expose properties and public methods.

Before:
  In a complex type:
    /**
     * @var string
     */
   public $var;

After:
  In a complex type:
    use BeSimple\SoapBundle\ServiceDefinition\Annotation as Soap;

    /**
     * @Soap\PropertyComplexType("string", name="var", nillable="true")
     */
    public $username;

    private $email;

    /**
     * @Soap\MethodComplexType("string", name="email", nillable="true", setter="setEmail")
     */
    public function getEmail()
    {
        return $this->email;
    }

    public function setEmail($email)
    {
        $this->email = $email;
    }

name, nillable are optionnal.
setter is optional and only available for MethodComplexType.
