Test case for queue-flow named queues sharing scope

var q = require('queue-flow');

function scanAll (data, callback) {
  console.log('scanAll with data:', data);

  var counter = 0;
  var items = [];

  var end = q();
  end
    .each(function() {
      oncedCallback(items);
      console.log('end');
    });

  var recurse = q();
  recurse
    .each(function(data) {
      data.Flag++;
      items = items.concat(data.Items);
      console.log('recurse - each items:', items);
      return data;
    })
    .branch(function(data) {
      return data.Flag > 1 ? end : recurse;
    });

  q([data]).branch(recurse);
}

scanAll({
  Items: ['X', 'firstScan-1', 'firstScan-2', 'firstScan-3'],
  Flag: 0
}, function(result) {
  console.log('first result:', result);
});

Updated output (appears to be working):

  Flag: 0 }
scanAll called with data: { Items: [ 'secondScan-1', 'secondScan-2', 'secondScan-3' ],
