Document 2D PDP and multinomial PDP

[exalate-issue-sync]

Add documentation of multinomial PDP. Users can use the new parameter targets if the model is multinomial. Targets parameter is an array and need contains the name of classes. If the user sets more than one class, all classes are plot in one graph in Python and R. In Flow only one target is supported right now.

It would be also nice to show the image of result 2PDP and multinomial PDP.

I implemented also python notebook to demonstrate multinomial PDP here:
