Comment (by vdelecroix):
I thought it was better standardization but in
`OA_from_quasi_difference_matrix` you have
{{{
# Each line is expanded by [g+x for x in line for g in G] then relabeled
# with integers. Missing values are also handled.
new_M = []
for line in izip(*M):
...
...
new_M = zip(*new_M)
}}}
what's the point?
