Function oner_induction::evaluate

pub fn evaluate<A: PartialEq, C: PartialEq>(
    cases: &[Case<A, C>], 
    attribute_values: &ArrayView<A, Ix1>, 
    classes: &ArrayView<C, Ix1>
) -> Accuracy

Evaluate cases (a.k.a., a rule) against a data set, to get a performance accuracy.

Accuracy is defined as the number of correct predictions over the number of rows.
