today: oblig 2 info (besides lecture), also on the net

Hi, today I plan to talk about O2.

the material is aslo available on the git-repos of the compila-compiler. It is there in the form of a ``patch'' for easy download.

See https://github.uio.no/msteffen/compila/tree/master/oblig2patch

(but if you still have the repository clone around, you can also fetch an update via git).

In the patch is also the sllides and the handout, I will talk about today.

Also those are web-accesible via https://github.uio.no/msteffen/compila/tree/master/doc/obligs
