Only the outlist specification I am not sure.
First, why can subsystem inputs be connected to system outputs?
Then, why was the specification and code in __init__ different from that
for the inplist?
I changed it to match inplist, but left the weird subsystem input configuration.
Check comment that starts with "Convert the output list to a matrix".
