Coding theory tutorial: many broken doctests

[nathanncohen]

The examples contained in the coding theory tutorial were never tested because they began with "Sage :" instead of "sage:".

This is reformatted in #17616 but many doctests were broken and were flagged as "not tested". Somebody who understands coding theory should go over them and fix them properly.

Even the sentence

Included in Sage is the group theory package GAP [GAP] and GUAVA [GUAVA], GAP’s coding theory package. All of GUAVA’s functions can be accessed within Sage.

is wrong, as GUAVA is optional, part of gap_packages.

It appears now "codes." must be preappended: for example,

C = ToricCode([[0,0],[1,0],[2,0],[0,1],[1,1]],GF(7))

becomes

C = codes.ToricCode([[0,0],[1,0],[2,0],[0,1],[1,1]],GF(7))

True. I believe that #17616 already does that wherever it is needed, though.

David, this should be fixed now, right?

Indeed.

All of these were fixed when I completely rewrote this tutorial in #19897.

I don't exactly know what to do in that case though. I know you can set a ticket as closed/invalid/wontfix which it more or less the case here, but I don't know how to do that.

Like this?

Yes, like this. It was under "milestones", of course...

Anyway, I'm giving a positive review to this closed/invalid/wontfix as the bugs described in this ticket does not exist anymore.
