/**
 * ByteBuddy MockMaker.
 *
 * This class will serve as the programmatic entry point to all mockito internal MockMakers.
 * Currently the default and only mock maker is the subclassing engine, but with enough feedback we can later
 * promote the inlining engine for features like final class/methods mocks.
 *
 * The programmatic API could look like {@code mock(Final.class, withSettings().finalClasses())}.
