numpy should not be referenced in the setup.py

[12rambau]

it's it the same vein as #37.

I've corrected some of the bug in my own fork but i'm now seeing another issue. At line

bfast/setup.py

Line 132 in 4fd0c17

from numpy.distutils.core import setup

, the setup.py file is calling numpy. But there are 0 guarantee that numpy will be available when installing the lib.

This file should only rely on Python built-in modules like distutils or setuptools.

If not refactored, the lib cannot be installed as in :

pip install -r requirements.txt

Yes, the setup script in general is a bit of a mess. It needs to be looked at.
