Finished version ready for implementation in Kaapana. I cleared the artefacts of old testing and technologies (bootstrap, boottrap-vue...). The animation for the clear button doesn't work
(don't know why...I wrote the methode and if you take a look in the console where I log the data which is changed in method you see it works correctly. But the changed data wheren't rendered... ).
The new POST method in the Kaapana API needs to be tested, but this is only possible if we integrate the app in Kaapana, because otherwise access will be denied.
