setup.py looking for setuptools module

I followed the directions in README.md but it fails at the step "python setup.py install" with error:

python setup.py install
Traceback (most recent call last):
File "/home/ericmedlock/Documents/python-work/numba/numba-examples/setup.py", line 1, in
from setuptools import setup
ModuleNotFoundError: No module named 'setuptools'

Start with the installation directions in README.md and the import at the top of setup.py. Reproduce the reported `python setup.py install` failure and determine how the missing setuptools dependency should be handled. Done means the documented installation path no longer stops at `ModuleNotFoundError`.
