@luigigisolfi Thanks for opening this PR! I think this functionality is going to make a lot of difference in setting up more complicated Tudat applications :)

I have a question/request, could we split it into two, with:

• One PR in tudatpy, containing the functionality of the automatic downloader
• One PR here with a (small) example of the automatic downloading
  I think the functionality you've set up is too valuable to have 'restricted' to the examples.

I can already go through the code and make comments/suggestions, so the two processes can run in parallel. If needed, someone (@alfonsoSR , @alopezrivera ?) could help out in how/where to add this to tudatpy. I think having this in the tudatpy.data submodule would be the most suitable. Your new functionality is all (?) contained inside a set of classes right?

Yes, that's correct. As it is now, users only need to import the required modules defined in the class file via:
from mission_data_downlaoder_class.py import *

This solution works for me! And yes, I could use some help from @alfonsoSR or @alopezrivera :)

What do you need help with? :)

Hey Alfonso! Thanks for this reply, I had missed it. Anywyay, I managed to implement everything myself.
We can now close this PR (#78), which will be superseded by PR (#82). PR #82 is meant to be combined with the tudatpy-PR #193.
