Actually, I can't get the tests working. The problem is the following:

• results/data_handler/data_handler.py needs DEFAULT_DATA_PROCESSORS for one of its class attributes.
• DEFAULT_DATA_PROCESSORS is defined in results/data_handler/__init__.py
• results/data_handler/__init__.py loads results/data_handler/data_handler.py
  This leads to a circular import.

I can't see a way around it. @yomach if you can't either then I suggest to cancel this PR, and keep DEFAULT_DATA_PROCESSORS in data_processors.py

@nulinspiratie See my changes.
Also note, I've put all of the __all__ under the __init__.py, as it is more customary to do

I am not sure I fully understand the status of this one, @yomach @nulinspiratie what is preventing us from merging or cancelling?
