Python 3 numpy warnings

[willblatt]

In Python 3.6.0, numpy 1.11.3, the following warnings appear:

C:\Users\######\AppData\Local\Continuum\Anaconda3\lib\site-packages\pydoe-0.3.8-py3.6.egg\pyDOE\doe_repeat_center.py:43: VisibleDep
recationWarning: using a non-integer number instead of an integer will result in an error in the future
.C:\Users\######\AppData\Local\Continuum\Anaconda3\lib\site-packages\pydoe-0.3.8-py3.6.egg\pyDOE\doe_factorial.py:78: VisibleDeprec
ationWarning: using a non-integer number instead of an integer will result in an error in the future

At least one of them appears to be due to this line in bbdesign:
nb_lines = (n*(n-1)/2)*H_fact.shape[0]

This line throws an error on my jupyter notebook (docker jupyter/minimal-notebook).
notebook server 5.0.0
Python 3.5.2
IPython 6.1.0

Fixed by using willblatt's fork:
pip install git+https://github.com/willblatt/pyDOE
Thanks

FWIW: I have found that there is now a pyDOE2 on pypi that is being maintained

Glad to see that pyDOE2 is available!!
