Lars Buitinck e1d4df43b0 FIX loss function example 
The Python API to the loss functions was lost in the last refactor.
Restored the example by defining the losses inline.
Fixed the x-axis to show "f(x)" instead of "y * f(x)".
Removed references to private APIs.

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
