kaichogami bd9716913e Made few tweaks based on commemnts 
changed docstring of partial_fit, added check_classification_target in ovo, removed classes parameter in _partial_fit_binary.

kaichogami cdb9dba63e Added doc, tests 
Added test for partial_fit when mini-batch doesn't have all target classes. Changed doc for better explaination of the use of  paramter in partial_fit method. Used generator for passing of classes in OvO in Parallel processing instead of estimator.pop().

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
