"pip install aptus" fails asking for numpy — setup_requires missing?

Hi Ned,

when trying to install aptus I get this error:

Could it be that setup.py is missing numpy in setup_requires? Should I make a pull request?

I don't have experience with setup_requires, so I used this low-tech approach. If that fixes it, I'd merge it. Thanks.
