Merge with current development version

For localization.py, a lot of new annotations were added to existing tests. If the tests were the same, I  took the new version (from develop), if the tests were different but the code identical I kept both, and if the tests and the code were different I kept the working version. I do not guarantee 100% consistency in that.
