scope all imports

Need to properly scope all imports

e.g.

import numpy as _np

Makes it much easier to change the import structure in the future

I would propose to remove the underscore in front, it's not really needed and makes code prettier :)

Agreed but it forms part of what is imported with a module. So if users mechanism is not reading (the code or manual) and just "tabbing" around different classes it clutters the available scope
