The NetworkOutput class will interface with a remote instance of the
Stereocam system (specifically, one using the NetworkInput class, described
in Section 4.2.2), and will transmit images passed
to PutImage() to the remote Stereocam instance. It will return false
when the network connection is broken or severed, for instance. The FinaliseImage()
method will send a message to the remote Stereocam instance, notifying it that
no more images are available.
