TYPE: POP
TITLE: SubNetwork POP

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

Sub-network POPs can also be nested within each other.

Parameters:
    Overview - The four string parameters allow labels to be specified for the
	       four inputs to the sub-network. 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
	       sub-network.
