"Level current view"

Did you merge the branch with the new "level current view" yet?

It is not here...

[constantinpape]

This is waiting on feedback from you since quite a while ago... #89

[constantinpape]

Also note that we decided to just use the view functonality for it and rename it to "anatomical views". See diff in #89 for details.
I will look into fixing the merge conflicts and could then merge it at any time, but please make sure that the "defaultLocation" in there works (we prematurely merged this at some point, which then prevented the whole project from loading)

Ok, I went ahead and merged the PR since solving the merge conflicts was a bit more difficult otherwise.
The project can still be opened and there is now "anatomical views->coronal" (which should correspond to the previous "level view") + the default location is in the json (field "defaultLocation").
I haven't checked if any of this works correctly in the viewer, so I am leaving this open for you to check.
