 /**
  * Merges a ContainerBuilder with the current ContainerBuilder configuration.
  *
  * Service definitions overrides the current defined ones.
  *
  * But for parameters, they are overridden by the current ones. It allows
  * the parameters passed to the container constructor to have precedence
  * over the loaded ones.
  *
  * $container = new ContainerBuilder(array('foo' => 'bar'));
  * $loader = new LoaderXXX($container);
  * $loader->load('resource_name');
  * $container->register('foo', new stdClass());
  *
  * In the above example, even if the loaded resource defines a foo
  * parameter, the value will still be 'bar' as defined in the ContainerBuilder
  * constructor.
