[Enhancement] Benchmarking JUnit tests

```
I think it would be great to have an integration with JUnit.
I'm looking forward to add @Benchmark to a JUnit test class and have all of the
@Test methods benchmarked, as well as integrating JUnit's @Before and @After
with @BeforeExperiment and @AfterExperiment.
Maybe an adapter for JUnit Runner?
I think it could give Caliper a boost. The Java community would love this.
What do you think?

Cheers.
