TISEAN is not maintained anymore, So inheriting bugs is just not good.
If TISEAN gets into Octave Forge I will take over maintenance with the
help of whoever is actively developing for it.
Also, I expect that in the long run TISEAN will eventually dissolve
into control, signal and tsa.

I will continue with the proposed methodology.
