setup.py imports numpy, but numpy is an install time dependency #144
Description
The setup.py file imports numpy which is an installation dependency. Because installation order cannot be specified (in order to ensure numpy is installed first), any package that depends on cf-units may also fail to install because numpy may not exist.
To reproduce the problem create a fresh virtualenv and run pip install cf-units which will result in:
pip install cf-units

Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-1f2to47t/cf-units/setup.py", line 7, in <module>
import numpy as np
ModuleNotFoundError: No module named 'numpy'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-1f2to47t/cf-units/
Therefore, cf-units is effectively broken for the standard python tool chain.
