Andrew Lamb 581056774a Fix check in `compute_class_weight`. 
In https://github.com/scikit-learn/scikit-learn/issues/4921, if a key in `class_weights`, a user-specified dictionary of classes, is not present in `classes`, an error should be raised.

Added unittest.

Robert Layton dacfd8bd5d DOC: Replaced all BSD style licenses with "BSD 3 clause" 
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
