* `demographic_parity()`, `equalized_odds()`, and `equal_opportunity()` are new metrics for measuring model fairness. Each is implemented with the `new_groupwise_metric()` constructor, a general interface for defining group-aware metrics that allows for quickly and flexibly defining fairness metrics with the problem context in mind.

* All warnings and errors have been updated to use the cli package for increased clarity and consistency. (#456, #457, #458)
