This is a tool that makes an add_layer or add_loss_layer object
expose only the part of its interface defined by the SUB_NET
expose only the part of its interface defined by the SUBNET
type in layers_abstract.h. This way, when we pass sub network
objects to the layer callbacks those callbacks won't be able to
interact with the sub networks in a way other than specified
by the SUB_NET interface spec.
