Multi-user support

[ricardobalk]

The app can currently only receive location updates from a single user. When authentication (see #1) is built-in, it becomes possible to provide multi-user support as well.

@ricardobalk I can work on that, after you update the read me for the new updates

[ricardobalk]

Sure @moogacs!

I have not updated all docs yet, but have written how to set up a development environment with this multi-branch approach. Basically, it comes down to having a good directory structure and editing some go.mod files, so Go knows to use the local packages instead of the online ones

You probably have to add some kind of authorization system to waarzitjenu/auth, then adopt waarzitjenu/server to use that functionality. That is what I had in mind for user management. But as always, feel free to design and develop your own ideas and implementations of it 👍

Brb, will make some commits to waarzitjenu/auth to init the repo! Done 👍
