 * NAME:        SHOP_Output.h ( SHOP Library, C++)
 *
 * COMMENTS:    Output nodes for SHOPs.  This probably doesn't have to be
 *      sub-classed off of SHOP_VariableInput since the number of inputs is
 *      fixed.  However, since it hides its unconnected inputs, it does a lot
 *      of the things that the variable input needs to do when the inputs
 *      change.
