Should the documentation be updated?

Indeed, the examples that are in the repository are out of date. We have had to release tudatpy well ahead of schedule due to unforeseen circumstances, and this is one of the points that is still on our long to do list. But, we should have this resolved in the coming weeks.

If you're interested in tudatpy, let us know what you plan to be using it for, it's always great to see people using our project! And, if you're interested there are a whole bunch of aspects of tudat(py) that you could contribute to if you're interested!

The bad experience proves that this is an immature project, maybe I should switch to other tools, such as Orekit, Celestlab, unless I need to use C++ or Python to build application scenarios.
