We made some progress over the weekend. It's not really functional but
you get a better idea. I decided to push this to master, hoping that
more people will look at it this way.

These are all done

That is stubbed out but doesn't work, yet.

I have much of that done. We don't do anything with that dive, yet, but
there are too many things missing in the user interaction, anyway, for
this to be useful.

If you now double click to create points and then drag them around
eventually deco will be added to the dive. There are odd visual
artefacts and there are a bunch of things that aren't right (I got it to
crash, once, but haven't been able to reproduce that).

So think of this as a WIP snapshot.
