Allow specification of percentages in test methods.

[meisterT]

A good unit test has only one assert statement. However, in practice we sometimes use more than one assert statement or the code before the assert fails for whatever reason (e.g. NPE in student code). In these cases, we'd like to give point percentages.

A possible annotation might be:

@Test(timeout=100)
@tester.annotations.Bonus(exID = "GA4.6a", bonus = 10)
public void test() {
    Student s = new Student(1, 2, 3);
    @tester.annotations.Checkpoint(0.2)
    Student s2 = new Student(s);
    @tester.annotations.Checkpoint(0.3)
    assertEqual(s.toString(), s2.toString());
}

So the whole test is worth 10 (relative) points in total. If you reach the Checkpoint, you will get proportionate values of that, even if the test method fails later on.

One might even allow variables in the checkpoint annotation (instead of constants only).
