Add a tutorial data method.

[SamTov]

What feature would you like to see added?
We could have a data loading method for the tutorials and CI built into MDSuite which just makes a temp directory, downloads some data and changes into the temp directory for further operations.

Describe how this feature would improve the code
It would make loading data really easy for our test cases and also fit nicely into the api.

Describe how this feature would work/possible implementations
Something like this currently exists in the green_kubo example found under MDSuite/examples/scripts

Is this resolved? We could also update the docs and give a small example for using DataHub / ZincHub.

We should sort out zincware/ZincHub#1 first.

I would not add any docs for using DataHub an Zinchub necessarily and would just write the examples using it. But yes this can be closed.
