Change `literature.tex` into `abstract.tex`

[dbosk]

Many of the literature.tex are of more abstractish form anyway. The abstract must contain the literature covered.

[dbosk]

The abstract should contain:

• a summary,
• the intended learning outcomes,
• prerequisites, if any,
• reading material.

This is being worked on in branch abstract.

The current idea (in the abstract branch) is that we have one abstract for the two lectures. Then one abstract per assignment.

However, another, maybe better, idea is to have one abstract for the module, i.e. the lectures and the assignments. Then we change the lectures and assignments into more integrated learning sessions. E.g.

• talk about risk analysis, assign the students to do something to next session,
• next session, use the results of the students' "homework".
