Organize and layout items based on various algorithms

// Add in top-down algorithm

  });
  return items;
};

  // Iterate over each of the items
  var y = 0;

    // Update the y to the current height
    item.x = 0;
    item.y = y;

    // Increment the y by the item's height
    y += item.height;
  });

  // Return the items
  return items;
