Unfortunately, the two imports in __init__.py are required for the rest of EasyScience to function.
Borg is pretty transparent, but the reason to import numpy from easyCore is a bit more murky. I think the idea was that at some point, modifications to numpy were expected, hence we wanted our version of numpy used.
However, none of those extensions have yet been implemented and we seem to be pretty negligent, using both from easyCore import np and import numpy as np throughout the code base.
This begs for standardization.

This looks good now!
