Essentially, the attached examples are applied wrt parametric Laplace F(s)
Parameters are wild and only specified ahead of invoked invLaplace(F(s),t).
Thus, algo is reusable from the function definition collapsed.
[a, ns, nd] are external. All attached are mutual companions.
1. One example must be NOT tinit 0
2. Gfails on range 0 .. 15 but succeeds 0 .. 20.
All in all: works fine. Rather for classroom, but useful for applications,
as exemplified [PID modeling, TurboGen].

Thanks Oscar, Alvaro ... Jean
