Quickstart Guides with a bit more on coding theory

[Johan Rosenkilde]

I wasn't before aware of the Quickstart Guides: http://doc.sagemath.org/html/en/prep/quickstart.html.

Coding theory is mentioned in the one on Graph Theory and Discrete Mathematics. A simple binary code is constructed with explicit matrix and examined for some combinatorial parameters. Would be nice to demonstrate decoding of e.g. RS code or something.

Ok, I add this to my todo list on documentation.
