Comment (by ncohen):

 Hellllooooo !!

 > I had trouble making the pdf documentation and then went back to devel
 branch to check it worked Ok there.  It did and then when I moved back to
 u/ncohen/16295 it worked.  I am not sure what happened

 Yeah, we had the same problems just one hour ago when Volker tried to
 merge #16277 or #16235... And it does not happen again because Sphinx is
 totall unreliable. I expect it to ocome from the dependencies, not from
 this ticket

 to verify it.

 Once this patch is applied there is no python version inside of
 `orthogonal_arrays.py`, as this patch removes it. We can add any doctest
 you want, but what could it be ? Remember that  this function is already
 tested a LOT by all constructions of OA/TD/MOLS as it is run on those
 instances every time one is built.

 > - it needs to have a doctest that demonstrates the speed improvement
 that cycthon gives over the purely python version inside
 orthogonal_arrays.py.

 Once more, this function removes the purely python one.
