TYPE: SOP
TITLE: SubNetwork SOP

The SubNetwork operation allows for the simplification of complex networks by
collapsing several operations into one. Four inputs are provided to
connect operations in the sub-network with operations in the parent network.

SubNetwork operations can also be nested within each other.

The four string parameters allow labels to be specified for the
four inputs to the SubNetwork. These labels appear when the
middle mouse button is depressed on the input connections and
will be useful to document the usage of each input to the
SubNetwork.
