This branch adds Python3 compatibility to NIFTy, while also staying compatible to Python2.
At the current state, the code compiles in both language versions and passes almost all tests.
Exception: some HDF5 tests, (1 fail with Python2, 5 fails with Python3). I need help with debugging those. [now fixed]
NOTE: An update to the "mpi_dummy" package is necessary to make it Python3 compatible as well. A merge request has been opened.
- the "hack" in the new method of SmoothingOperator, which returns a DirectSmoothingOperator or an FFTSmoothingOperator depending on the arguments, stopped working with Python3. I have put together a crude workaround, but this could still be improved.
Things to do:
- enhance continuous integration to test Nifty with Python3 [done now]
