> A score function for Predictor implementations should take a DataSet[(I, O)] and an (optional)
scoring measure and return a score.
> The DataSet[(I, O)] would probably be the output of the predict function.
> For example in MultipleLinearRegression, we can call predict on a labeled dataset, get
back predictions for each item in the data, and then call score with the resulting dataset
as an argument and we should get back a score for the prediction quality, such as the R^2
score.
