What is the idea?

Given the context of #622 we need to split outputting (for debugging) from rendering.

Why is this needed

see #622

What should happen?

This task is to remove the current implementation that mixes rendering vs. output and add support for defining where to output.

Note: As part of this we should also separate the set/unset of the stdout and stderr from the code execution (right now they are mixed together with one single call to runPython
