TYPE: CHOP
TITLE: SubNetwork CHOP

This CHOP allows for the simplification of complex networks by collapsing
several CHOPs into one. Four inputs are provided to connect CHOPs in the
sub-network with CHOPs in the parent network.

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

There are no local variables.

Parameters:
    Input 1-4   - 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.

    SubNet CHOP - This menu designates exactly one CHOP within the
                  subnet as the default output.
