[HECnet] HECnet map

As I've also told Paul in private, I this is really great. It's been on my wish-list for many years, but have not always been so easy to figure out how to do. Paul did some impressive work on PyDECnet, and now added this, making it really nice! Thanks a lot. I hope people can look at it and be a bit impressed on how far HECnet spreads out. And of course, there is also the possibility for people to see if they might benefit from getting some links up in cases where they can see that they are really connected though some odd place from their point of view. And to just briefly also give a bit of tech information. The positional data is extracted from the nodename database I have on Mim, so if people spot they are placed wrong, or out in the south Atlantic, all you need to do is give me a better position, and I'll update the nodename database, and you will magically be corrected on the map as well (within a day or a week, depending on how often the generated map is updated). ?
