/**
 * Apply this annotation to any method without parameters to have it timed as a macrobenchmark. A
 * macrobenchmark is roughly defined as any benchmark whose runtime is large enough that the
 * granularity of the {@linkplain System#nanoTime clock} is not a factor in measurement. Thus, each
 * repetition of the benchmark code can be timed individually.
 *
 * <p>Additionally, since each rep is independently timed, setup and tear down logic can be
 * performed in between each using the {@link BeforeRep} and {@link AfterRep} annotations
 * respectively.
