- Ability to provide both class properties and method-specific parameters via
  configuration (which solves disambiguation when multiple methods specify the
  same parameter names)

  Proposed solution:

        array(
            'properties' => array(
                'Zend\Foo\Bar' => array(
                    'public' => true,
                    'methods' => array(
                        '__construct' => array(
                            'params' => array(
                                'foo' => 'bar',
                            ),
                            'class' => 'Some\Default\Class'
                        ),
                        'setConfig' => array(
                            'params' => array(
                                'bar' => 'baz',
                            ),
                        ),
                    ),
                ),
            ),
        )

- Ability to pass configuration to a generated ServiceLocator
- Skip optional arguments if not passed in configuration or part of definition
  (current behavior is to raise an exception if *any* arguments are missing)
-
