Title: implemented predict_proba for OneVsRestClassifier

This also involved writing function `predict_proba_ovr` to mimic the
methodology of existing code.

Note that in the multilabel case, the marginal probability of the sample having the given label is returned. These probabilities do not sum to unity, since the set of such probabilities over all labels do not partition the sample space.
