Bridging the two systems views
In Seq.Algebra I need a representation of a system to be able to
compute a Z transform (or generate a Seq function that computes the Z
transform, which might be useful for things like graphical display).
How to match that with the requirement of Seq, to implement closeReg?
Actually, Z transform is just function evaluation. It is probably
also not necessary to distinguish between linear and non-linear,
because it will simply not be defined for nonlinear functions.
