Creating the n most important pairwise plots!

[AndreBiedenkapp]

The following line causes an issue

fanova/fanova/visualizer.py

Line 282 in 9860cdc

most_important_pairwise_marginals = self.fanova.get_most_important_pairwise_marginals(n)

get_most_important_pairwise_marginals has two optional parameters, where n is the second one. As the first optional parameter expects a list of strings and the n parameter is an int it always throws the following error:
TypeError: 'int' object is not subscriptable

If the line gets changed to "...get_most_important_pairwise_marginals(n=n)" everything should work fine.
