Queue add callback
==================

This example shows how to use queue callbacks. It sends both mono frames and color frames from the device to the
host via one :code:`XLinkOut` node. In the callback function :code:`newFrame()` we decode from which camera did
the frame come from so we can later show the frame with correct title to the user.
