Spurious print statements in library code

[cpehle]

There are a few spurious print statements in the library code, which ideally should be converted into log output, one example is

hbp-neuromorphic-client/nmpi/nmpi_user.py

Line 385 in 97ded63

print("Job submitted")

The library is really intended to be used interactively in a Jupyter notebook, so the print statements are not spurious in this context.

I agree though it would be a good idea to have an easy way to turn them off.
