Added ns-3 docset.

[tnull]

I added a docset for the ns-3 network simulator.
However, the ns-3.tgz is around 2.5 GB, so I'd need somewhere to upload it before the PR can be accepted.

Regards!

I uploaded the ns-3.tgz, you can pull it from: https://tnull.de/static/ns-3.tgz

2.5 GB is a bit too large unfortunately. Any idea what's causing the size? The docset has around 2400 classes, so it shouldn't be quite that large.

I think the size comes mostly from huge number of png files. These should be inheritance graphs and collaboration diagrams generated by doxygen/dot. Should I exclude them? Then, however, the documentary might be broken at some points (as in you would see that there is something missing).

[Kapeli]

Maybe configure Doxygen so it doesn't generate graphs at all?

[tnull]

Yep, I disabled some variables (but I think setting HAVE_DOT = NO should be enough) and was able to push the file size of ns-3.tgz to 72 megabytes. See the updated commits! :)

Great. Please fix these issues though:

Not 16x16: "icon.png" in "ns-3"
Not 32x32: "icon@2x.png" in "ns-3"

[tnull]

Done. Strange, each of the icons were exactly twice as large. Must have done sth. wrong while saving them.

Thank you! 👍
