ValueError is being propagated to the cross_val_score/predict and grid
search

FIX Fabian's comments
PEP8
This test passes under Python 2.7 but currently fails under Python
3.2+. This change of behavior makes many doctest fail under Python 3
while they pass under Python 2.
The goal of this test is to help find the cause of the issue under
Python 3 and also act as a non regression test once a fix is found
under Python 3.
Replaced all BSD style licenses with "BSD 3 clause"
Not checked yet!
Removed duplicate "3 clause, 3 clause"
Removed trailing period if exists
Fixed some missed licences, still about 50 to do, but those can be automated
Think I got the last of them.
Apparently me and sed have different ideas of regex.
Found a few more
