Thu May 5: going through parts of the Oblig

Thanks for your efforts with the Oblig (delivered Tue 3rd). I'll manage to go through them all in the course of today (Wed 4th), and will then use *part of the time* tomorrow, Thu 5th, to go through the Oblig material.

In addition, we start out on the state space models, Sections 6.1, 6.2, 6.3, the last part of our curriculum.
