Clean dev

[ProkopHapala]

• removed all my non-essential WIP projects (like forcefield relaxation, multipole fitting, density compression, OpengGL visualization and CorrectionLoop) ... they are backed up in branch prokop-dev
• moved some test files into /test folder (I created new one ... I was thinking you olready created one? Maybe it is in different Branch? There may be conflict?)
• some test files were created by you
• my test file for tip-spline are meant to be checked by human eye (not automatically), therefore I created sub folder tests/human_eye ... what you think about ti ?
• there was sub folder /fitPPM which is from @yakutovicha (as far as I know). So I wait for him to confirm I should delete it (it is backedup in prokop_dev branch) ... or he may decide to do something else with it

Just keep it there, I will make a follow-up PR to move those.

@ProkopHapala, Before we start reviewing, can you update your master branch and merge it into clean_dev? It is a bit behind currently.

OK, but in the process I somehow accidently merged clean_dev to main
