Use standard JUnit4 annotations.

Consider if we can kill the custom annotations in favour of using @Before, @After and @BeforeClass from JUnit4. Would this make sense and would the semantics be clear?

Hi @nlativy! I came across this project and I'm considering implementing this enhancement -- is this something that's still worth pursuing for the project? And if yes, do we want to deprecate the custom annotations and still support them, or just remove them completely?
